Rats with a bacterial infection are trained to consume immunity-suppressing and nausea-producing cyclophosphamide in saccharine-flavored water.

This modification of the immune system is an example of which of the following?
A. Operant conditioning
B. Classical conditioning
C. Avoidance training
D. Adversive experience
E. Overwhelming stress
