apostrophes
none of the above

Answer 1

All possessive nouns contain an apostrophe

Answer 2

Apostrophes

Step-by-step explanation:

A possessive noun is a noun that possesses something—i.e., it has something. In most cases, a possessive noun is formed by adding an apostrophe +s to the noun, or if the noun is plural and already ends in s, only an apostrophe needs to be added.
