In VCRS heat rejected from condenser to surrounding fluid (Q1) is summation of work given to the compressor (W1) and heat extracted (Q2) from the space which is to be cooled.
Q1= (W1) + (Q2).
Q1= (W1) + (Q2).

Yes, Work done = Heat absorbed-Heat rejected.

Ya, the answer will be C, because, heat absorbed + work done = heat rejected.
Ahmed said:

Yes C, Because Heat absorbed + work done in it = heat rejected.

In refrigeration heat rejected is more than heat absorbed because its function is cooling a substance so for cooling we used reverse cycle.

Heat absorbed + work done in it = heat rejected. So that's the matter.

For cooling purpose it is essential that heat rejected is more than heat absorbed.
