An antipyretic is:

Answer 1

Hint:An antipyretic is a chemical substance that reduces fever. Antipyretics cause some process in body due to body. Antipyretics cause the hypothalamus to override a prostaglandin-induced that increases temperature of the body. Then, the body works to lower the temperature, which results in a reduction in fever or reduces the temperature of the body.

Complete step by step answer:
Quinine is a chemical compound used for treatment of malaria, a disease caused by parasites. Quinine can’t reduce the body temperature and it is only used for treatment of malaria. That’s why it is not an antipyretic.
Paracetamol is a chemical compound used as a painkiller used for treatment of pain and aches. But paracetamol also reduces the body temperature due to which it is also used for treatment of sickness. Then, it also reduces fever and it is an antipyretic.
Luminal controls the abnormal electrical activities in the brain and mainly used to control anxiety. It doesn’t reduce body temperature and it is not an antipyretic.
Piperazine is also not antipyretic.
Hence there is only paracetamol which is an antipyretic and the correct answer is option B.

There are also some more antipyretics such as aspirin and ibuprofen which are used to reduce fever. These drugs are available in many forms such as tablets, capsules, powder, liquid, etc.
