The right answer is B

The term "amphetamine" refers to a class of chemically related stimulant substances. First synthesized in the 1880s, amphetamines were originally used as a remedy for decongesting the nose, losing weight, and helping people stay awake.

Amphetamine abuse can also trigger aggression, mood swings, irritability, sleep disturbances and uncontrollable urges. Long-term symptoms include dysthymia, a mood disorder that is characterized by chronic depression or irritable mood.

Other symptoms may include appetite and sleep disturbances, fatigue, low self-esteem, depression, mood swings, uncontrollable cravings, lethargy and sleep disturbances.
