b. acetylcholine
c. dopamine
d. serotonin
mark for review (will be highlighted on the review page)

Explanation:

To solve this, we analyze each neurotransmitter:

• Epinephrine (A) is related to stress response, not primary for depression.
• Acetylcholine (B) is involved in muscle function and memory, not depression's main target.
• Dopamine (C) is linked to reward/motivation, but serotonin is more associated with depression's neurotransmitter deficit.
• Serotonin (D) is known to be reduced in depression, and anti - depressants (like SSRIs) target serotonin reuptake to increase its availability.

Answer:

D. Serotonin
