Which of the following medications is commonly prescribed to treat depression?

Antidepressants are commonly prescribed to treat depression because they target the brain's neurotransmitters, such as serotonin and norepinephrine, which are believed to be imbalanced in individuals experiencing depressive disorders. These medications work by helping to improve mood, relieve anxiety, and stabilize emotions. They are specifically designed for the treatment of depression and related mood disorders, making them the most appropriate choice in this context.

Analgesics are primarily used to relieve pain and do not address the underlying causes of depression. Antifungals are medications used to treat fungal infections and have no role in managing depressive symptoms. Similarly, scabicides are used to treat infestations of scabies and are not relevant to mental health treatment. Thus, antidepressants are clearly the best choice among the options provided for the treatment of depression.
