Option A, extrinsic motivation, is the right answer.

Explanation:

The meaning of the term Extrinsic is coming or managing from outside and motivation is the reason an individual has for performing or acting in a specific way. If we combine both the words we will find that Extrinsic motivation is the behavior which is controlled from outside i.e. rewards such as grades, money, popularity or recognition. This form of motivation is different from the intrinsic motivation where the motivation is self-generated.

In the given situation, Marion is receiving the motivation from outside therefore, option A,  extrinsic motivation, is the right answer.
