A. classical conditioning.
B. primary reinforcers.
C. latent learning.
D. delayed reinforcers.

D. delayed reinforcers

Explanation: The student's attitude best point out that human behavior is influenced by delayed reinforcers.

Delayed reinforcement can be simply defined as the time lapses or delay between the delivery of rewards and the desired response of an individual, this rewards are called reinforcers. If the rewards are presented after a delayed period of time, that reward is called delayed reinforcer.

Explanation:

Right from when we are much more younger, when you do something either bad or good there is always a reward for us and this is the concept in Psychology. When you do something good and you are giving something to compensate you for what you have done then we say that that you have been Reinforced and that concept is called Reinforcement in Psychology.

Reinforcement may be fast that is immediately or delayed. So, just as the words "immediate" and "delayed'', immediate Reinforcement is when the reward to specific action is fast and delayed Reinforcement is the reward to specific action is not fast just like the case for the students. Their reward for hardwork was good grade at the end of the semester.
