Which of the scenarios below is an example of extrinsic motivation?

A)Auditions are being held for a local community theater production. You have never participated in anything like this before but would like to give it a try.

B)The audition is a blast. Cooking is something you think you might be good at, so you volunteer to look up recipes, make a shopping list, and prepare two meals during the week.

C)Your dog's behavior has gotten really bad lately, and you want him to behave better. You sign up for an obedience class that the two of you will complete together.

D)Your sister is volunteering her time for a local charity and wants you to help, too. You have other charitable interests but help her anyway because you feel it is the right thing to do.
