Answer:
d. the Premack Principle
Explanation:
This is an example of the Premack principle. The Premack principle is a theory of reinforcement which is employed in order to help a person engage in a more desired behaviour. This theory comes from psychologist David Premack. The Premack principle works by using two behaviours. The idea is that a high probability behaviour will reinforce a less probably behaviour. In this example, the highly probable behaviour of having to mow the lawn discourages Sam from going to the arcade.
