Topic: Adjective (বিশেষণ),

Best Answer Explained in Below-:

The word "prolific" is classified as an adjective because it describes a noun by conveying a quality or characteristic. In English, adjectives are words that modify nouns, providing more information about them, such as their qualities, quantities, or states. "Prolific" typically refers to someone or something that produces a large amount of something, often within a specific context, such as creativity or productivity. For example, one might refer to a "prolific writer" to indicate that the writer produces a substantial volume of work, such as books, articles, or stories.

In contrast, verbs express actions or states, while nouns represent people, places, things, or ideas. Since "prolific" does not convey action nor does it stand as a person, place, or thing, it cannot be classified as a verb or noun. Therefore, option B is the correct answer, as it accurately identifies "prolific" as an adjective that enhances our understanding of the qualities inherent in the subject being discussed.
