Topic: Pronoun (সর্বনাম),

Best Answer Explained in Below-:

The words "my," "our," and "her" are classified as possessive pronouns, which indicates ownership or a relationship to something. In grammatical terms, they show possession of a noun, answering the question "whose?" For example, in the phrase "my book," "my" demonstrates that the book belongs to the speaker. Similarly, "our" signifies collective ownership, while "her" indicates that something belongs to a specific female individual.

To elaborate on the other options:

- The nominative case (Option A) pertains to the subject of a sentence, typically pronouns like "I," "he," or "she."
- The dative case (Option B) usually marks the indirect object of a verb, often associated with words like "to" or "for," and is less relevant for possessive concepts.
- The objective case (Option C) applies to pronouns when they are the object of a verb or preposition, using words like "me," "him," or "them."

Since "my," "our," and "her" explicitly indicate ownership or belonging, they are correctly categorized under the possessive case, making Option D the right choice.
