I suppose NH3 is the refrigrent and water is absorbant. So answer should be NH3 not aqua ammonia.

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

LiBr use water as refrigerant.

Right answer is Ammonia.

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).

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.

The Right answer is NH3.

Only NH3 is the right answer.

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

No. It will be ammonia only.
