Topic: Pronoun (সর্বনাম),

Best Answer Explained in Below-:

In the sentence "Who is the man that come to you?" the term "that" functions as a relative pronoun. A relative pronoun is used to connect a clause or phrase to a noun or pronoun, providing additional information about that noun. In this case, "that" introduces the relative clause "that come to you," which gives us more information about "the man." It specifies which man we are discussing—namely, the one who came to you.

Understanding the roles of pronouns helps clarify their usage:

- Indefinite pronouns refer to non-specific entities (e.g., someone, anything).
- Demonstrative pronouns point to specific items (e.g., this, that, these).
- Interrogative pronouns are used to ask questions (e.g., who, what, which).

In contrast, relative pronouns like "that," "who," and "which" serve to link additional information back to a noun. Thus, in this context, "that" clearly serves the function of a relative pronoun, making option D the correct answer.
