Answer (C) is correct because our body is a good conductor of electricity and it has even been mentioned in the synopsis. Now, that means that (i) is correct so automatically B and D get canceled. The air in no form acts as a conductor and is an insulator. So C is also canceled. This leaves us with our final aswer A.
