It may increase or decrease depends upon range of pressure and degree of superheating.

In practically, if superheat temp is 5- 6 ° cel then cooling effect will increase and compressor work needs more compare than increase Colling effect. So COP reduces.
If the degree of superheat less than 5 then work input negligible. So cop increases.
If the degree of superheat less than 5 then work input negligible. So cop increases.

Answer C is right (decreases COP).

Due to the superheating refrigerating effect (R.E) increases and also work done in the compressor increases. But R.E. is less compared to w/D so the net effect is to have decreased in cop.

D because it depends on refrigerant.
In some cases, it increases and some cases decrease.
In some cases, it increases and some cases decrease.
