Which of the following is an example of an intrinsic motivation?

A) writing a story just for the fun of it
B) writing a story to submit to a magazine for pay
C) writing a story because your instructor requires you to write it
D) writing a story to submit for a competition

Intrinsic motivation refers to the desire to engage in an activity for its own sake, rather than for some external reward or pressure. Writing a story just for the fun of it is an example of intrinsic motivation, as there is no external reward or pressure to do so. Choices B, C, and D involve external rewards or pressures (money, fulfilling a requirement, competition), and thus do not represent intrinsic motivation.
