Topic: Adjective (বিশেষণ),

Best Answer Explained in Below-:

In grammar, possessive adjectives are words that modify nouns to show ownership or possession. They are used to specify to whom something belongs. In the options provided, the correct answer is A) "This is his car."

In this sentence, "his" is the possessive adjective modifying the noun "car." It indicates that the car belongs to a male person. Other examples of possessive adjectives include "my," "your," "her," "our," and "their," each signifying ownership by the respective person or group.

Let's analyze the other options to understand why they do not contain possessive adjectives.

B) "That book is mine" uses the possessive pronoun "mine," which, unlike adjectives, stands alone and does not modify a noun directly.

C) "It's a business of their's" incorrectly uses "their's," which is a common misspelling of "theirs," a possessive pronoun, and lacks the adjective form.

D) "This house is belongs to them" contains a grammatical error and lacks a possessive adjective; instead, it incorrectly mixes a possessive meaning with verb conjugation.

Therefore, option A is the only sentence that correctly demonstrates the use of a possessive adjective, illustrating ownership directly tied to the noun it modifies.
