Topic: Adverb (ক্রিয়াবিশেষণ),

Best Answer Explained in Below-:

In the sentence "She looks very beautiful," the word "very" functions as an adverb. Adverbs modify or describe verbs, adjectives, or other adverbs, providing more context about how an action is performed or the degree of a characteristic.

In this case, "very" modifies the adjective "beautiful," enhancing its meaning by indicating the extent of her beauty. By using "very," the speaker expresses that her beauty is not just noticeable but is at a significant or impressive level. Without "very," the sentence would simply state that she looks beautiful, but with it, the emphasis on the degree of beauty is noticeably stronger.

To clarify the other options: "adjective" refers to words that describe nouns (e.g., "beautiful"), "verb" indicates action words (e.g., "looks"), and "pronoun" replaces nouns (e.g., "she"). Therefore, the correct answer is D) adverb, as "very" modifies an adjective, providing essential detail about the nature of the beauty being described.
