Topic: Adjective (বিশেষণ),

Best Answer Explained in Below-:

In the sentence “He was a rather ‘disagreeable’ man,” the underlined word ‘disagreeable’ functions as an adjective. Adjectives are words that describe or modify nouns, providing more information about their characteristics, qualities, or states. In this case, ‘disagreeable’ describes the noun ‘man,’ indicating a specific quality about him—namely, that he is unpleasant or not agreeable in nature.

To further clarify, the structure of the sentence includes a linking verb ‘was,’ which connects the subject ‘He’ to the subject complement ‘a rather disagreeable man.’ Here, 'rather' is an adverb that intensifies the adjective, suggesting a degree of disagreeableness. Since the word ‘disagreeable’ provides a descriptive quality to the noun and conveys information about the subject, it is classified as an adjective.

Therefore, among the options provided, option B—Adjective—is the correct answer, highlighting the word’s role in the sentence as a descriptor of the noun ‘man.’
