Answer:
The accurate statement is b. "Don't let the energy into the fridge!"
Step-by-step explanation:
Heat is energy. Inside a fridge there is lower heat - lower energy - than the surroundings. The spontaneous transference of energy is always from a place with higher energy (hot) to a place with lower energy (cold). So, as the frigde is cold, the heat is transferred from the surroundings to the fridge.
