Which pronouns include "who," "whom," and "which"?

The selection of "who," "whom," and "which" as relative pronouns is accurate because these pronouns are specifically used to introduce relative clauses, which provide additional information about a noun. Relative pronouns connect a clause or phrase to a noun or pronoun, acting as the subject or object within that clause. For example, in the sentence "The book that I read was fascinating," the word "that" serves to link the clause to "the book," giving more information about it. Similarly, "who" and "whom" relate to people, while "which" is typically used for objects or animals.

In contrast, demonstrative pronouns such as "this," "that," "these," and "those" are used to point to specific nouns but do not introduce additional descriptive clauses. Personal pronouns like "I," "you," "he," "she," "it," "we," and "they" are used to refer to specific people or things in a sentence but do not serve the same function as relative pronouns. Indefinite pronouns such as "some," "all," "many," and "few" refer to non-specific items or quantities and also do not introduce relative clauses.
