【求教】OG 4 的一个问题

4. The only way for growers to salvage frozen citrus is to process them quickly into juice concentrate before they rot when warmer weather returns.
                

(A) to process them quickly into juice concentrate before they rot when warmer weather returns

(B) if they are quickly processed into juice concen­trate before warmer weather returns to rot them

(C) for them to be processed quickly into juice concentrate before the fruit rots when warmer weather returns

(D) if the fruit is quickly processed into juice concen­trate before they rot when warmer weather returns

(E) to have it quickly processed into juice concentrate before warmer weather returns and rots the fruit

想请问B中to rot这个用法有问题吗？感觉to do有强烈的意愿倾向，可是主语是weather，觉得别扭。。。
