Answer 1

Answer: B. Release of dopamine within the accumbens is a necessary condition for reinforcement

Explanation:

Dopamine: It is one of the neurotransmitters produced by human body. Biologically this dopamine is the reason for pleasure experiences.

Reinforcement is nothing but wanted stimulus. Whenever we see wanted stimulus, our body automatically releases dopamine neurotransmitter. That dopamine will reach accumbens in the brain so that we are experiencing pleasure. That's why this pleasure will be associated to that reinforcement.
