Topic: Sentence (বাক্য),

Best Answer Explained in Below-:

The question "Why did mother punish Michael?" is the most appropriate choice in this context because it seeks to explore the reason behind the action taken by the mother. The original statement indicates that Michael was punished due to his behavior—specifically, because he "had been bad." Understanding the motivation behind the mother’s decision adds depth to the situation, as it provides insight into the underlying rationale for punishment, which typically aims to correct or address bad behavior.

In contrast, the other options focus on identifying the subject or confirming the action rather than exploring its rationale. For example, options A and B inquire about who was punished, which is already clear from the statement. Option C asks for confirmation of whether Michael was punished; this is also evident in the original sentence. Hence, selecting option D aligns best with the intention of seeking additional context or rationale behind the statement, making it the most insightful and relevant question.
