Question

Choose the correct possessive form for the underlined noun.

The man shirt was stained.
A. mans'
B. man’s
C. mans
D. men’s

Answer 1

either A or B. "The man's shirt was stained." makes more sense to me. So try A.

Answer 2

The answer is B, man's.
The answer is not A because an apostrophe after the "s" signifies that the subject is plural. In this case, the subject is singular, so the apostrophe before the "s" is appropriate. Hope this helps!
