Hint: Lysergic Acid Diethylamide or LSD is a class of drugs and is termed as acid in common terms. This drug alters the serotonin system in humans. Use of LSD can change how a person feels, thinks and perceives his environment.

Complete answer:
LSD or Lysergic Acid Diethylamide is a class of hallucinogenic drugs. It is known to affect the Serotonin system of human beings and results in a change of feeling, perception of the surroundings and the ability to think. An individual may also start imagining things around him. Clinical changes post LSD consumption include higher blood pressure, Dilated pupils and an increase in body temperature. LSD was previously used for medicinal purposes. At present, it is not used for medical purposes, but only in recreational activities. Thus, we can say that LSD is a hallucinogen.
Sedative and tranquilizers are depressants of the Central Nervous System. They function by inhibiting the actions of neurotransmitters. Usually, sedatives are used by medical professionals to negate pain and anxiety. However, sedatives or tranquilizers do not relieve the patient from pain, instead they depress the action of CNS so that pain is not felt by them. Misuse or overdose of these drugs can cause deep sleep, unconsciousness and even death.
Opiates are substances that are derived from opium. Opiates are obtained from the opium poppy plant known as Papaver somniferum. They are alkaloid compounds. The commonly used opiates are morphine, codeine and thebaine. These drugs do not generally affect the central nervous system of human beings. Opiates are used primarily to relive individuals of pain by medical professionals.
Stimulants are a class of huge numbers of drugs that are used for a variety of medical purposes. However, stimulants are consumed as prescription and without prescription drugs. Stimulants can function to increase vigor, sociability and increase the ability to focus. These drugs can also enhance the performance of individuals consuming them. However, stimulants are banned from competition or use by college students.

Therefore, we can conclude that LSD is a hallucinogen and option (C) is correct.

Note: Lysergic Acid Diethylamide or LSD is an illegal drug, manufactured by laboratories in the form of white powder or crystals. It causes a hallucinating effect on the person consuming it. LSD affects the CNS and functions to change one’s mood and thinking abilities. A person may also start hallucinating under the effect of LSD.
