Which fallacy does the following passage commit?

a. professor fallon has asked us to purchase a coffeemaker for her office.
b. but we shouldn’t do that because next she’ll want a microwave, and then a convection oven.
c. then she’ll want a full-sized refrigerator, a sink with hot and cold water, a dishwasher, and a complete set of expensive china.
d. this will exhaust the budget of our department.

The correct answer is:

Causation fallacy (Oversimplification or exaggeration fallacy)

This fallacy is also known as fallacy of reduction or multiplication

Explanation:

The oversimplification or exaggeration fallacy is used to appeal  the fact that one single act would unchain several consequences of the same type without any cause to link it as a real proof of the possible occurrence. In this case, it is simple a prediction that is not based on any type of fact or scientific evidence to prove that this will certainly happen.
