Explanation:

A toaster is an electrical appliance. When it operates, it uses electrical energy. The purpose of a toaster is to heat bread, which means it converts the electrical energy it consumes into thermal (heat) energy. Thermal energy to electrical energy is the opposite of what a toaster does. Electrical to nuclear energy is incorrect as there is no nuclear reaction in a toaster. Electrical to chemical energy is also wrong as there is no chemical energy storage or production in the typical operation of a toaster for heating bread.

Answer:

electrical energy to thermal energy
