Question

Which words in the sentence are the complete noun clause? For a long time, no one knew where tuna spawned. A. no one knew where B. tuna spawned C. where tuna spawned D. for a long time.

Answer 1

The answer is C, where tuna spawned. A noun clause is a dependent clause that essentially fills the role of a clause. Since a noun clause is dependent, it does not form a complete thought or full sentence when pulled from the master sentence.

Answer 2

I would say the answer is C. Actually am not a native english speaker but I think its the answer.
