Because condenser purpose is used to cool vapor.

May be by evaporator as this is the main aim of refrigerant cycle.

Heat is rejected by the refrigerant at the condenser.

Heat is rejected by the expansion valve not in condenser, the function of condenser is to cool the refrigerant not to reject heat, because this function is of expansion valve.

No dear, heat is rejected in the condenser and refrigerant is converted.

Vapour form to liquid form(Phase change by removing latent heat). Temperature remain constant during phase change.

Because condenser can be used for the cooling purpose.

In expansion valve only pressure drop and temperature drop takes place.

The right answer is condenser.

Condenser is not only used for cooling purpose but it also rejects heat.

Check question
Where is heat rejected by the REFRIGERANT?

The refrigerant passes through
1. Compressor -and gets super heated -so absorbs heat
2. Condenser - converted to saturated liquid - rejects heat
3. expansion valve - throttling process no heat absorption or rejection.
4. Evaporator - evaporates to vapour form - thereby absorbing heat from space to be refrigerated.

So, it is now clear that where the refrigerant rejects heat.

Well said @Vivekraj. Thanks.

Heat is rejected from the condenser.

Thanks @Vivekraj.
