e
Inhibits the presynaptic neuronal uptake of serotonin and norepinephrine and prolongs the effects of the monoamines in the synaptic cleft

b
Inhibits serotonin re-uptake in the synaptic cleft
QuestionChoice

c
Blocks oxidative deamination to cause the accumulation of endogenous catecholamines
QuestionChoice
