how is ownership shown for singular nouns? (1 point)
add -s to the noun
add -es to the noun
add -s to the noun
add an apostrophe if the noun already ends in -s

Explanation:

To show ownership for singular nouns, we use the possessive form. For most singular nouns, we add -'s. Adding -s or -es is for pluralizing nouns, not showing possession. Adding just an apostrophe for a singular noun ending in -s is incorrect (that rule applies to plural nouns ending in -s). So the correct way is to add -'s to the singular noun.

Answer:

C. add -'s to the noun
