In vapour compression cycle, the condition of refrigerant is very wet vapour

In evaporetor at the when all liquid vaporied, C is appropriate answer

If refrigerant is very wet vapour before entering the compressor then due to moisture present in the refrigerant there will be wear and tear of the moving parts inside the compressor due to sudden expansion of heat inside the compressor.
Hence, option D is incorrect.
Answer: Option C.

Option D is not correct because of very wet vapour getting after throttling or expansion

Option c is correct condition refrigerant is very wet after passing through the expansion valve and before entering the compressor dry saturated vapour

correct answer is C option. Refrigerant is in dry saturated or even superheated before entering the compressor

Ya options C is the right ans .
If u don't know about it then how u can ans strongly.

... The refrigerant is become wet vapour at the stage of entering to evaporator

All option are wrong.... The refrigerant is become wet vapour at the stage of entering to evaporator

Option (C) is right.
Before entering the compressor it becomes Dry saturated vapour.

Option C is the right answer
