Which of the following is an example of extrinsic motivation?

Extrinsic motivation refers to engaging in an activity not for its own sake, but rather to achieve an external outcome or reward. In this case, completing a task to earn a reward exemplifies extrinsic motivation, as the focus is on obtaining something external, such as praise, money, or another tangible benefit, instead of finding inherent satisfaction or joy in the activity itself.

This contrasts with intrinsic motivation, which is illustrated by options like reading a book for enjoyment, practicing a skill to improve personal achievement, or engaging in a hobby for personal fulfillment, all of which focus on internal rewards and personal satisfaction derived from the activities themselves.
