Which word is the simple subject of the sentence?

The proud parents of the goalie cheered loudly from the stands.

A.

goalie

B.

parents

C.

loudly

D.

stands

To correctly answer the question we must know that a simple subject is the main word or word group that tells the reader what the sentence is about. This is in a way a small scale version of explaining the main character of a book. In this sentence, the sentence is about the parents of the goalie as they are the ones cheering not the goalie or anyone else. Loudly is an adjective not a noun, thus, it can not be the answer. The stands can not be an answer either as they are not what the sentence is about.
