The question is asking what the ligament must be. Therefore, the ligament is the only thing that can balance the birds wings. The wings are driven by powerful forces, which we can read in the first sentence of the passage. Answer choice B says that the ligament is the reason that the birds wings must be stable. However, even though the ligament keeps the wings stable, it isnt the reason for it. The reason would be that the ligament is a reason for the bird to fly, but not for keeping the wings stable.

Im definitely interested!!
