Which word is a singular noun? a) athletic b) men c) clowns d) dancers

I believe you have a typo when it comes to the first option - it should be athletics, not athletic. The word athletic is an adjective, and the word athletics is a noun.

That being said, the correct answer is A. athletics. Even though this noun ends in - s, it is still singular. The rest of the options are all plural nouns.

Hi.

your answer will be athletics.

It is not given in the options.

Athletic is adjective that describes noun.
