Sir, right now HFCs are used in refrigeration and it has higher green house potential and recently it concluded under Kigali agreement; so, i have doubt whether it should be HFC or HCFC in the question.

Yes Jignesh you are right ..It is HFC which is substitute for CFC,HCFC which are Ozone depleting substances due to Chlorine atom. This CFC,HCFC were replaced by HFC ...but this is having higher warming potential ...though it is not Ozone depleting substance. In the option it should be HFC instead of HCFC... So none of the options are correct
