Respuesta :
The Answer Is ( The UN Building Has More Flags Than Rooms )
Answer: B) The UN building has more flags than rooms.
Explanation: An elliptical clause ("than rooms.") has been used here to avoid repetition of the verb "have"; the full sentence would be "The UN building has more flags than [it has] rooms." Since this clause is a modifier of the verb "has," it has an adverbial function, therefore it is an elliptical adverb clause.
