Topic: Adjective (বিশেষণ),

Best Answer Explained in Below-:

In the sentence "Dina is a wise girl," the word "wise" serves as an adjective that describes the noun "girl." Adjectives are words that modify or provide more information about nouns, indicating qualities, characteristics, or states of being. In this case, "wise" conveys a specific quality of Dina, suggesting that she has good judgment and insight, which are characteristics associated with wisdom.

To further clarify, let's look at the other options:

A) Noun: A noun is a person, place, thing, or idea. "Wise" does not represent any of these categories; rather, it describes a noun.

B) Adverb: Adverbs modify verbs, adjectives, or other adverbs, often indicating how, when, where, or to what extent something happens. "Wise" does not serve this function in the sentence.

D) Pronoun: A pronoun replaces a noun (e.g., he, she, it), which "wise" does not do.

Since "wise" qualifies and describes the noun "girl," it is correctly identified as an adjective. Thus, C is the correct choice.
