Which sentence uses the word 'his' as a pronoun?

Rule: Possessive Pronoun Usage:

- Possessive pronouns show ownership or possession. They replace a noun and indicate who something belongs to.

Application to the Sentence:

- In the sentence, 'his' is used to indicate possession and represents the possessive pronoun for the noun 'problems.' It shows that the problems belong to him.

Explanation of Options:

- ক - "His is a unique problem": In this option, 'his' is used as a possessive pronoun, but it's followed by the article 'a' and the adjective 'unique.' The sentence structure doesn't fully align with the use of 'his' as a pronoun.

- খ - "This is his area": In this option, 'his' is used as a possessive determiner, indicating possession before the noun 'area.' It is not used as a pronoun here.

- গ - "His problems are his, not yours": This option correctly uses 'his' as a possessive pronoun, representing ownership of the problems mentioned in the sentence.

- ঘ - "a and c": While option গ is correct, option ক uses 'his' in a different grammatical structure, and the conjunction "and" does not connect them appropriately.

Therefore, option গ, "His problems are his, not yours," demonstrates the correct usage of 'his' as a possessive pronoun.
