Question

Which sentence contains an incorrect possessive form?

A.
The lawn mower's spark plugs needed to be replaced.

B.
Foxes' dens are usually well hidden.

C.
The design appealed to most viewers' tastes.

D.
A dog headed toward the sheeps' pen.

Answer 1

The incorrect possessive is in D: the sheeps' pen.

Sheeps is not a word: the plural of sheep is just the same: sheep. So the possesive of this should be sheep's. Pronunciation would be the same as sheeps', but the spelling is different.
