B) a small toaster oven toasts a bagel.

C) rubbing two sticks together.

D) sunlight heating a metal door.

A small toaster oven toasting a bagel is the correct answer. A toaster works by using electrical energy. We know this because the toaster has a plug that we have to connect to the electrical current before it can operate. This electrical energy, however, gets turned into heat energy, demonstrated by the fact that our bagel is warm and toasted when we take it out of the oven.
