A and B are correct.

I think option D should be All of the above.
1) COP of what? Heat pump always >1 coz
Cop(HP)=1+COP(R)
COP of R can be less than 1
2) It's superheated vapor.
3) its superheated vapor region.
So, all are false.

In case of absorption, refrigeration system COP may be less than 1 and also some time in the air refrigeration system.

Option A will be correct here because we need to select the wrong statement here. So option A is wrong becuse COP is not always greter than 1.

Answer = option C.
The space between the saturated liquid line and saturated vapour line in a pressure enthalphy chart is superheated vapour region.
Over there they mentioned wet vapour region so it's the wrong statement.
