The correct answer is option (b) Both A and R are true, but R is not the correct explanation of the assertion.

• Quinine is a drug obtained from cinchona bark that is used chiefly in the treatment of Malaria, an infection caused by the protozoan parasite Plasmodium, which is transmitted to humans by the bite of various species of mosquitoes.
