You have seen it on tests, academic papers, business surveys, and even job applications. The phrase “which of the following” is one of the most widely used expressions in the English language. Yet many writers and students still struggle with it.
Should you write “which of the following is” or “which of the following are”? Is “which of the followings” ever correct? How do you use this phrase in formal writing without sounding robotic?
This guide answers every one of those questions with clear grammar rules, real life sentence examples, and practical tips you can use immediately.
What Does “Which of the Following” Mean?
The phrase “which of the following” is a fixed expression used to introduce a set of options and ask someone to choose one or more correct answers from that list. It functions as an interrogative determiner, meaning it introduces a question that expects a selection.
In plain terms, it tells the reader: “Here are some choices. Pick the right one.”
You will find this phrase in:
- Multiple choice exam questions
- Academic research papers
- Business surveys and questionnaires
- Legal documents and policy forms
- Online quizzes and assessments
The phrase is built from three parts:
| Part | Function |
| Which | Interrogative pronoun asking for a specific choice |
| of | Preposition connecting “which” to “the following” |
| the following | Noun phrase referring to the list of options that come next |
Together, they form a structure that points to a defined, known set of items. This is what separates it from a general question like “what is correct?” — the word which already signals that the options are right in front of you.
How to Use “Which of the Following” Correctly
The phrase always appears at the beginning of a sentence and is immediately followed by a verb, usually is or are. When you introduce a vertical list of options, follow the phrase with a colon. When the sentence flows in a single line, no colon is needed.
With a colon (list format):
Which of the following are primary colors? a) Red b) Orange c) Blue d) Green
Without a colon (inline format):
Which of the following cities is the capital of Japan, Tokyo or Osaka?
The phrase can also appear in embedded or indirect questions within a longer sentence:
Please indicate which of the following options best describes your experience.
In that example, the phrase sits inside a statement, not a direct question, so no question mark is needed at the end.

Is It “Which of the Following Is” or “Are”?
This is the most common point of confusion. The answer depends entirely on what comes after the verb.
<cite index=”29-1″>Use “is” when expecting a single answer and “are” when expecting multiple answers or when the subject that follows is plural.</cite>
Here is a simple rule to follow:
Look at the word or noun that comes immediately after “is” or “are.” If it is singular, use “is.” If it is plural, use “are.”
Examples:
| Sentence | Correct Because |
| Which of the following is a mammal? | Asking for one item (a mammal) |
| Which of the following are mammals? | The noun “mammals” is plural |
| Which of the following is the correct answer? | One answer expected |
| Which of the following are correct statements? | Multiple statements possible |
A helpful tip: if the question targets one specific correct answer, go with is. If it invites selection of multiple right options, choose are.
Which of the Following Is Not
The negative form, “which of the following is not,” is very common in standardized testing. It asks the reader to identify the option that does not belong to the category described.
Examples:
- Which of the following is not a planet in our solar system?
- Which of the following is not a function of the liver?
- Which of the following is not considered a renewable energy source?
<cite index=”24-1″>Experts advise using negatively stated stems sparingly, and when you do use them, it helps to highlight the word NOT in bold or caps so test takers do not overlook it.</cite>

- Highlight negative words. If you use NOT or EXCEPT, put it in bold or caps.
- <cite index=”19-1″>Keep crucial words visible. Mark key terms in bold or caps so test takers do not miss them.</cite>
- Avoid giving unintentional clues. Do not make the correct answer noticeably longer or grammatically different from the wrong ones.
