Choose the correct possessive form for the underlined noun. One person role could not be decided. A. persons' B. person's C. persons D. people's

The answer is B. Person's

Possesives for nouns are formed by adding 's to a singular noun (Like person's) or a plural noun ending in any letter but s (like men's), and just adding ' to a plural noun ending in s (like cars')

Answer: The correct possesive form for the noun "person" is B. person's.

Explanation: The possesive in English is formed by adding an apostrophe and an "s" to a noun. Taking this into account, option B. (person's) is the one that provides the correct possesive form for the noun "person" since it includes an apostrophe and an "s" immediately after this noun. In contrast, option A. is incorrect because the "s" should be added after the apostrophe. Moreover, option C. is also incorrect because it does not include the apostrophe: it only presents the plural form of "person". Furthermore, option D. changes the noun from "person" to "people", which is also incorrect.
