Lowest temperature during the cycle in a vapour compression system occurs after condensation or throttling.

Yes, you are right @Nikunj Miyani.

D is right because in evaporator latent heat is transfer so the temperature remains same only phase change occurs.

In general the lowest temperature in any refrigeration cycle is occur after the EXPANSION process only. But in the answer mentioned that is after evaporation.
In the process of evaporation the refrigerant collect latent heat from bodies.

Both B and D answers are right. Because in evaporation, Refrigerant Absorbs latent heat at constant pressure. Only state changes, not temperature.

It's after expansion.

Due to sudden drop of pressure at expansion the temperature also drops but after expansion latin heat is received during the evaporation so correct answer is Expansion.

Lowest temperature is caused after the condenser.

Both answer are correct.
As during evaporation latent heat is added.
