Thanks @Muhammad.

No. It will be ammonia only.

Aqua ammonia is the strong solution which works as a refrigerant. So, Answer is correct.

Only NH3 is the right answer.

The Right answer is NH3.

But only Ammonia provides the refrigerating effect.

If we consider water as a refrigerant than we also have to consider Li-Br as refrigerant along with water.

In the case of Water-lithium bromide vapour absorption refrigeration system, Water is refrigerant and Lithium bromide is an absorber.

In the case of Water-Ammonia vapour absorption refrigeration system, Water is absorber and Ammonia is a refrigerant.

So, the correct answer should contain both "Water" (Aqua) and "Ammonia" and according to the given options, the options D suits best but it should be like (Aqua, Ammonia) instead of (Aqua-Ammonia).

Right answer is Ammonia.

LiBr use water as refrigerant.

No the refrigerant itself is a mixture of water and ammonia apart from absorbent.
