Which of the following scenarios best explains "stimulation-based intrinsic motivation" as it is described in the Point essay?
A. You finished a tricky 9x9 Kenken puzzle.
B. You learned French subjunctive conjugation in time for your trip to Paris.
C. You baked your first pumpkin pie from scratch for Thanksgiving and it was delicious.
D. Your uncle gave you $20 for mowing his lawn.
I believe it is A because puzzles are a mentally stimulating activity and intrinsic-motivated activities mean that you do them for the process and not for the end reward.
