Topic: Sentence (বাক্য),

Best Answer Explained in Below-:

The question, "What were the Lacons known for?" directly seeks to elicit information about the characteristics or notable attributes of the Lacons. This matches the original statement perfectly, which specifically mentions that "The Lacons were known for their bravery and short speeches." Option C effectively asks for clarification on the very subject matter presented in the statement, making it the most relevant choice.

In contrast, option A simply repeats the statement without adding any inquiry or seeking clarification, rendering it less relevant as a question. Option B, "Who were known for their bravery?" is vague and doesn’t specify the Lacons, making it irrelevant to the original content. Lastly, option D, "What were the Lacons?" is incomplete as it fails to specify what aspect of the Lacons is being questioned, leaving it open-ended and lacking direction.

Therefore, option C stands out as the only choice that accurately and directly asks for the information provided, making it the most logically correct answer.
