Topic: Pronoun (সর্বনাম),

Best Answer Explained in Below-:

In the sentence, "He looked at himself in the mirror," the pronoun "himself" functions as a reflexive pronoun. Reflexive pronouns are used when the subject and the object of the verb refer to the same entity. In this case, "he" is the subject performing the action of looking, and "himself" refers back to the same individual, indicating that he is looking at his own reflection.

Reflexive pronouns typically end in "-self" or "-selves," and their primary role is to emphasize that the action of the verb is directed back to the subject. This distinguishes them from emphatic pronouns, which also include "-self" forms but serve to stress the subject rather than indicate that the subject and object are the same.

Options B, C, and D can be ruled out as follows: Emphatic pronouns emphasize a subject ("He himself did it"), distributive pronouns refer to individuals within a group (e.g., "each"), and relative pronouns introduce subordinate clauses (e.g., "who," "which"). Thus, "himself" is correctly identified as a reflexive pronoun, making option A the right answer.
