A.it B.which C.use D./

this is the main use that the scientists make ____ of natural resources.A.it B.which C.use D./
最好的解释在这里
make use of 是固定搭配,表示利用……的用处
这里是定语从句,先行词是use,
use 在 定语从句中充当宾语的成分,也就是充当 make 的宾语,
因为定语从句中,这个词要省略的,
这个词在定语从句中是 that,that 是定语从句的关系代词,就是先前的use
所以答案D

D

对呀，本来是选c的，但是一看前面已经有了个use了，也就是说use给提前了，使用就选空的了
