'D' is correct, since drugs either stimulate (increase) or inhibit (slow down) normal physiology at the synapse. Example of stimulating are L-dopa for treating Parkinson's. Example of inhibiting is a calcium channel blocker for heart problems. And yes, drugs effect mood - look at all the depression meds that are out there.

I'm not a doctor but I'd guess d.
"... a class of drugs known as selective serotonin re-uptake inhibitors or SSRIs affect certain synapses by inhibiting the re-uptake of the neurotransmitter serotonin. In contrast, one important excitatory neurotransmitter, acetylcholine, does not undergo re-uptake, but instead is removed from the synapse by the action of the enzyme acetylcholinesterase."

The answer is D (all of those options can be an effect depending on the drug you take)
