Final Answer :
A
Explanation :
Nicotine is an agonist for acetylcholine, meaning it mimics the action of acetylcholine at its receptors, and it generally causes postsynaptic potentials (PSPs) that can lead to increased neuronal activity, which might explain Malcolm's increased smoking habit as a way to self-medicate or manage concentration issues.
