In actual, at the end of the evaporator, we always get superheated vapor which is obviously greater than the temp of the refrigerant after expansion.
Therefore the temp of the refrigerant is lowest after expansion. So, option B is correct.

After taking latent heat, the enthalpy is increased but temperature remains same.

After expansion, before entering to evaporator the ref temp may go down to -15 °C.

A/c to T-S diagram, lowest temperature should be after expansion or throttling.

Yes, the temperature is constant during evaporation but within the dome, when constant pressure line crosses the dome then he goes in the superheated region and here temp is not constant, so the most appropriate answer is after expansion.

After"Expansion" Low temperature occurs.
After"evaporation " Low temperature to normal temperature because of heat addition occur during evaporation. So, answer is option (A).
