Answer:
b. impulse product
Step-by-step explanation:
An impulse product is the one that people buy in the spur of the moment though they didn't plan to do it. This is something retailers take advantage of by placing certain products like candies close to the checkout counters that can get to a purchase by impulse. In this case, for Camille, Twinkies are an example of impulse product because she didn't have them in the shopping list but she decided to buy them at the last moment when she saw a display in the checkout line.
