Isaac has had insomnia for six months and when he goes in for his regular check-up,he asks his family doctor if there is something that can be prescribed to help him fall asleep.If his doctor does prescribe a medication,what is it most likely to be

A)  barbiturate 
B)  amphetamine 
C)  narcotic 
D)  hallucinogen

Barbiturates are a class of sedative drugs that can be used to treat insomnia. They work by depressing the central nervous system, causing drowsiness and promoting sleep. However, they can also be habit-forming and have the potential for overdose, so they are usually only prescribed for short-term use under careful medical supervision. Amphetamines, narcotics, and hallucinogens are not typically used to treat insomnia.
