Identify the clause in the underlined portion of the given sentence: Can you…

Answer: Noun Clause.

Explanation: The underlined clause "who wrote the Panchtantra" begins with the wh-word who and contains a subject and verb, so it is a clause. It functions as the object of the verb "tell" in the sentence (Can you tell me [who wrote the Panchtantra]?), therefore it acts like a noun.

• Forms an indirect question introduced by a wh-word; this is a common pattern for noun clauses.

• Functions as the direct object of "tell me," so it has a noun role in the sentence.

• It is not an adjective clause because it does not modify a noun, not an adverb clause because it does not modify a verb/adjective/adverb in the typical subordinating way, and not a principal clause because it is subordinate here.
