Final answer:
Sonya's physician prescribed Valium for her. Sonya most likely has b) Anxiety.
Step-by-step explanation:
Sonya's physician prescribed Valium for her, which is a benzodiazepine medication used to treat anxiety disorders. Anxiety disorders are characterized by excessive and persistent worry or fear that is out of proportion to the situation and interferes with daily functioning. Valium works by enhancing the effects of a neurotransmitter called gamma-aminobutyric acid (GABA), which helps to calm the brain and reduce anxiety.
Other medications commonly used to treat anxiety disorders include alprazolam (Xanax), lorazepam (Ativan), and clonazepam (Klonopin). Therefore the correct answer is b) Anxiety.
