Topic: verb (ক্রিয়া),

Best Answer Explained in Below-:

The word "sympathise" is identified as a verb because it describes an action or a state of being. Specifically, it refers to the act of sharing or understanding the feelings of another person, particularly in times of sorrow or hardship. In English, verbs are words that indicate actions, occurrences, or states of being, and "sympathise" clearly fits this definition as it conveys the action of empathizing with someone else's emotional experience.

In contrast, the other options provided do not accurately categorize "sympathise." An adjective (Option A) describes a noun and provides information about its qualities but does not express an action. A noun (Option C) represents a person, place, thing, or idea, which is not applicable here since "sympathise" does not denote a tangible entity. Lastly, a preposition (Option D) indicates the relationship between nouns or pronouns and other elements in a sentence, which "sympathise" does not fulfill.

Thus, recognizing "sympathise" as a verb is essential to understanding its role in communication, reflecting the dynamic process of emotional connection and response.
