Answer

B

Explanation

Analgesics reduces or abolish pain without causing impairment of consciousness, mental confusion, incoordination or paralysis or some other disturbances of nervous system. Analgesics are non-narcotic or narcotic. Narcotic analgesics when administered in small doses relieve pain and produce sleep. Tranquilisers are a class of chemical compounds used for the treatment of stress, and mild or even severe mental diseases. Histamine is a substance which on release produces hypersensitivity to dust, some drugs etc (i.e., allergy). Antihistamines are the drugs which interfere with the natural action of histamine by competing with histamine for binding sites of receptor where histamine exerts its effect. They are anti-allergy drugs.
