In What Way Is Classical Conditioning Different from Sensitization in Aplysia

In what way is classical conditioning different from sensitization in Aplysia?

A) Sensitization is specific to touching the siphon, while classical conditioning generalizes to stimulation of other areas.
B) Sensitization is due to changes in the number of synapses, whereas classical conditioning is due to changes within the cells.
C) The siphon-withdrawal response is larger following classical conditioning than it is after sensitization training.
D) Sensitization involves an increase in glutamate release, whereas classical conditioning involves a decrease in glutamate release.
