Morphine
As an animal model of exercise addiction, ABA is frequently explored. Endorphins are released when you exercise. Exercise addiction is thought to be influenced by the rise in endorphins.
According to the theory, the fact that exercise raises endorphin levels causes exercise addiction. A medication that stimulates this neurotransmitter would make ABA-induced rats less prone to run in their wheels (because their endorphin levels would be elevated by an alternative method).
The only medication that is an endorphin agonist is D, or morphine, thus it is clear that this is the right response.
