Solution
The correct option is B Cocaine - Depressant Cocaine is a stimulant that increases the function of the CNS (central nervous system) leading to a state of awakening. Cocaine is obtained from the coca plant, Erythroxylum coca.
Morphine is an opioid derived from the opium of the poppy plant, Papaver somniferum. Opioids are a class of drugs that are classified as depressants as they bind to opioid receptors in the body and slow down the body functions. Morphine is a sedative and painkiller and usually prescribed for the cancer-related pain.
LSD is a hallucinogen that alters the senses and perception.
Hence, option b is incorrect as cocaine is a stimulant but not a depressant.
