I think answer is wrong , use of tourniquet was preferred method until few years ago , it has been found it can damage blood flow and nerves

Ans 2:

Class : Class 5
souvik is saying 'avoid giving water to the person in case of poisoning so the poison does not spread in the body. and tying torniquet just above the wound will spread the poison more. so, the answer should be C

Ans 3:

Class : Class 3
Answer is wrong, Souvik is saying 'avoid' while the answer is giving a different explanation .All Samrak, Souvik and Shivani are wrong.

Ans 4:

Class : Class 5

Ans 5:
