The right answer is the B: Infinitive clause. You have to ask yourself this question: What did the band ask everyone? And the answer is "to look to the second stage." That is an infinitive phrase, since it includes an infinitive, "to look" (the infinitive is the form of a verb that has not been conjugated), and a complement, and it functions as a noun, specifically acting as a direct object - the thing that the band asked.
Hi,
