Which drug is an MAOI?

Explanation:
MAOIs inhibit monoamine oxidase, the enzyme that breaks down monoamines like serotonin, norepinephrine, and dopamine. By blocking this enzyme, these neurotransmitters accumulate in the brain, helping improve depressive symptoms. The drug that does this is phenelzine, a classic irreversible MAOI. The others are SSRIs, which work by blocking serotonin reuptake rather than inhibiting MAO, so they are not MAOIs.
