Question

Choose the correct use of the apostrophe.

People in their _____ are often trying to establish careers in the workplace.

A.
20’s

B.
20’

C.
20s

D.
20s’

Answer 1

People in their 20s are often trying to establish careers in the workplace.

In this sentence, 20 is supposed to be plural (because there are multiple years from 20 to 29). Having an apostrophe would indicate possessive behavior, and 20 does not "have" or "own" anything in this sentence.

Answer 2

I think it would be A. 20's.


I'm not quite sure why, but just common sense, sorry if it isn't convincing.
