A. a, B. c, C. ac, D. bc
D: bc
Answer: D: bc 
Explanation: Fast EPSP in autonomic ganglia are generated by Acetylcholine on nicotinic cholinergic receptors.
Slow EPSP in autonomic ganglia are generated by Acetylcholine on M1 muscarinic receptors.
Slow IPSP in autonomic ganglia are generated by Catecholamines (Dopamine, noradrenaline) on dopaminergic, α- adrenergic and M2 muscarinic receptors.
