I answered no because I did not know what A-1's intent was since the question only referenced B-1. If the ball hit off A-1's inner thigh, who was perhaps just standing and did not intentionally attempt to kick the ball, why would this be a kicking violation? the correct answer was yes.

I think this must have been a typo of some kind.

I have no explanation for the others. I await enlightenment from someone wiser and more experienced than myself.
