Answer:unconditioned stimuli
Pavlov fed dogs and was looking at salivation in response to the food.
At a certain point, whenever he entered the
room, the dog would start to salivate even when he was not bringing them
food. The exact same happened to Dionne when she saw the chili peppers even though it was just a picture and not the real thing.
This it is an unconditioned response to an unconditioned
stimulus.
I would say A because it sounds the most positive and sometimes people need a little push to get confidence to follow their dreams and be successful.
