A chemical agent is found to denature acetylcholinesterase in the synaptic cleft, a space between nerve cells that neurotransmitters cross to cause signaling. What effect will this agent have on the neurotransmitter, acetylcholine?

(A) Acetylcholine will not be released from the presynaptic membrane into the synaptic cleft.
(B) Acetylcholine will not bind to receptor proteins on the nerve cell across the synaptic cleft.
(C) Acetylcholine will not diffuse across the cleft to the second cell.
(D) Acetylcholine will not be degraded in the synaptic cleft.
