Repolarization of a postsynaptic cell can occur when:
A) there is a high enough concentration of neurotransmitters in the synaptic cleft.
B) neurotransmitters undergo exocytosis from the presynaptic cell.
C) enzymes degrade neurotransmitters in the synaptic cleft.
D) neurotransmitters are not removed from their receptors.
