Topic: Sentence (বাক্য),

Best Answer Explained in Below-:

In the context of the dialogue between A and B, the question posed by A is inquiring about the presence of people in the bar. The phrase "Are there any people in the bar?" is an interrogative sentence expecting a response regarding the existence of people in that location.

The proper response to A's question needs to validate or negate the existence in a way that stays consistent with the question's structure. Among the provided options, "B) there aren't" is the correct choice because it appropriately responds to A's question with a negative statement. This response confirms that, according to B, there are no people present in the bar.

Option A, "any," does not complete the thought and lacks grammatical coherence as a standalone response. Options C, which is a repeat of B, is also correct but redundant. Meanwhile, option D, "are there," incorrectly turns the conversation back into a question instead of providing an answer, making it inappropriate for the context.

Thus, "there aren’t" effectively communicates B's answer, directly addressing A's inquiry and maintaining proper conversational structure.
