Explanation:

Subordinate clauses are groups of related words having a subject and a verb that does not express a complete thought on their own, and therefore, should always be with another clause in order to make sense. Option B has those characteristics. This clause has a subject which is “ancient forest” (the function of “that” is to refer to that subject) and a verb: “grew,” and if we removed this clause from the sentence, the clause would not make sense because it does not express a complete idea on its own

Furthermore, this clause is an adjective clause because it gives us information about the noun “ancient forest.”

are there multiple choice options?

wrong! the answer is c.
