Which of the following statement is correct?

A. In vapour absorption refrigerator, the compression of refrigerant is avoided.

B. Sub-cooling can be achieved by circulating more quantity of cooling water through the condenser.

C. In vapour compression refrigeration, the vapour is drawn in the compressor cylinder during its suction stroke and is compressed adiabatically during the compression stroke.

D. All of the above
