An adverb clause is a group of words containing a subject and a verb, and it functions as an adverb, by modifying an adjective, verb or an adverb. Adverb clauses generally begin with a subordinate conjunction (since, because, while, etc.)
Option B is correct because it is an adverb clause of comparison ('than' is a comparative adverb).
Option A is incorrect because it is a phrase, not a clause.
Option C is incorrect because it contains a coordinate clause, whereas an adverb clause is subordinate.
Option D is incorrect because the answer lies in B.
