Answer:
Option B, anxiety
Step-by-step explanation:
Alprazolam, better known by brand name Xanax, is an anti-anxiety medication of the benzodiazepine classification that acts by producing an anxiolytic effect on the central nervous system (CNS) as well as depressing this system's activity, both of which are believed to be mediated by the inhibitory neurotransmitter known as gamma-aminobutyric acid (GABA).
As the type of medication may suggest, this medication is primarily indicated in the relief of anxiety symptoms, and because of this is deemed to treat anxiety, option B.
