请教92.01的一道语法题

The Kettledrum produces different tones depending on whether _____ with sticks that have felt or sponge heads.

A to strike

C it is struck

why choose C instead of A? I remember the usage of whether to V. is acceptable too.

虽有 whether to V.形式，但这里是不能用的，因为语态都不一样． whether 指的是 felt or sponge heads，it is struck是后面从句的主谓语．
