Motor Neurons Release the Neurotransmitter Acetylcholine ACh), and Acetylcholinesterase Degrades

Motor neurons release the neurotransmitter acetylcholine ACh) , and acetylcholinesterase degrades ACh in the synapse. If a neurophysiologist applies onchidal a naturally occurring acetylcholinesterase inhibitor produced by the mollusk Onchidella binneyi) to a synapse, what would you expect to happen?

A) gradual loss of resting potential
B) decrease in the frequency of action potentials
C) paralysis of muscle tissue
D) convulsions due to constant muscle stimulation
E) no effect
