关于it指代不明~~

Many entomologists say that campaigns to eradicate the fire ant in the United States have failed because the chemicals that were used were effective only in wiping out the ant's natural enemies,which made it easier for them to spread.

Awhich made it easier for them
Bwhich makes it easier for it
Cthus making it easier for them
Dthus making it easier for the ant
Ethereby, it was made easier for the ant
A
我明白其它选项错误的原因，可是D里的it指代的是什么呢？？这个不算指代不明么？

it是形式宾语，真正的宾语是to spread，整句话的意思是making (to spread) easier

it作为形式宾语就不存在指代不明的问题了咯？那在哪些情况下it是形式宾语？？
