Vedclass · Answer

(B) The Assertion is correct. Cocaine is an alkaloid obtained from the coca plant, $Erythroxylum 	ext{ } coca$. It interferes with the transport of the neurotransmitter dopamine,resulting in a potent stimulating action on the central nervous system,which produces a sense of euphoria and increased energy.The Reason is also a correct statement regarding immunology. Active immunity is indeed developed when a host is exposed to antigens,which can occur either through natural infection or through intentional exposure via immunization (vaccination).However,the Reason does not explain the mechanism of action of cocaine. Therefore,both statements are correct,but the Reason is not the correct explanation of the Assertion.
