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 A is correct because it is an adverb clause of place, "where" refers to place and it has the subject "I" and verb "used to sit".
Option B is incorrect because it is not an adverb clause of place, but that of time (while).
Option C is incorrect because it is not an adverb clause of place: it's a phrase.
Option D is incorrect because the answer lies in A.
