Which of the following are relative pronouns?

Relative pronouns are a specific category of pronouns that introduce relative clauses, providing additional information about a noun or pronoun mentioned earlier in the sentence. The correct choice accurately lists the words commonly recognized as relative pronouns, which include "who," "whom," "whose," "that," and "which."

Who and whom refer to people, with "who" often acting as the subject and "whom" as the object of a verb or preposition. "Whose" expresses possession, while "that" and "which" can refer to things or animals, distinguishing between restrictive and non-restrictive clauses. This nuanced understanding of how these pronouns function and the meanings they convey is essential for constructing grammatically correct sentences that provide clarity and detail. Thus, this option successfully encompasses the comprehensive nature of relative pronouns in the English language.
