Final answer:
The possessive case pronoun from the options provided is A) Their, which is used to show ownership, such as in “Their suitcases and Their vacation.” Pronouns come in three cases: subjective, objective, and possessive, and 'Their' is indeed possessive.
Step-by-step explanation:
The question you've asked is about identifying a possessive case pronoun from the given options. A possessive pronoun is used to indicate ownership or belonging. Out of the options A) Their, B) Them, C) Themselves, and D) You, the pronoun that is used in the possessive case is Their. For example, in the sentence “The family packed their suitcases for their vacation,” both the suitcases and the vacation belong to the family, which is indicated by the use of “their.”
Pronouns are categorized into three cases: subjective, objective, and possessive. A subjective case pronoun functions as the subject of a sentence, like “I” or “we”. An objective case pronoun functions as the object of a sentence or preposition, such as “me” or “them.” Therefore, based on these conventions, the correct option in the final answer for a possessive case pronoun is A) Their.
