An apostrophe may be used correctly to form a a. possessive b. contraction c. plural d. both a and b above, but not c

The right answer is letter d. An apostrophe is correctly used as a contraction or possesive but never as a plural.

d. both a and b above, but not c

Explanation:

Apostrophes can be used to form possessive case it order to indicate possession; for example:

the neighbours' house

the children's bedroom

the man's car

Besides, apostrophes mark contractions, such as the verb to be and auxiliary verbs like has, have, had and would, in affirmative and negative forms:

Mary's a good student.

I've been to London twice.

She hasn't finished her homework yet.

When I got home, they'd already had dinner.

I'd like a cup of coffee, please.

On the other hand, regular plural forms do not take apostrophe but the suffix -s.

book - books

dog - dogs

memory - memories
