Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A) : Large cold storage plants use ammonia as refrigerant. While domestic refrigerants use chloroflourocarbons.

Reason (R) : Ammonia can be liquified at ambient temperature and low pressure.

In the light of the above statements, choose the most appropriate answer from the options given below:

Both (A) and (R) are true and (R) is the correct explanation of (A)

Ammonia and chlorofluorocarbon are indeed used as refrigerants, but not for the reasons outlined in (R).

The reason industrial refrigeration systems prefer ammonia over chlorofluorocarbons is due to its superior thermodynamic qualities, not just its ability to be liquified at low pressures.

Large cold storage plants do use ammonia while domestic refrigerators use chlorofluorocarbons in their cooling systems - thats assertion (A), which is true. While its true that Ammonia can be liquified at ambient temperatures at low pressures, its not the reason why its used as a refrigerant.

Large cold-storage plants do use ammonia as a refrigerant and domestic units use chlorofluorocarbons.

The correct answer is Option (1) → Both (A) and (R) are true and (R) is the correct explanation of (A)
