By executing this strategy of rewarding the actions leading to the desired behavior Darren is using C) shaping to get his son to eat his peas.

Explanation:

In other words, it establishes the whole expected behavior process and reinforces all o the desired behavior stages until it only reinforces the expected behavior. It is a very effective way to condition the behavior the executor expects.
