Question

Which sentence contains an error in the use of apostrophes?

A.She has difficulty writing 2s and 5s.

B.Don't forget to cross all of your t's.

C.The two ?s in that sentence are a mistake.

D.The Is stand for the word incomplete.

Answer 1

All of them are incorrect other than B. So the answer is B.

Answer 2

I wanna say B is wrong. Using the apostrophe before the s usually signifies a sense of belonging, but the T is not possessing anything.
