The Correct Option is A

Solution and Explanation

Explanation:
Refrigerator is a device that transfers heat from inside a box to its surroundings. If you leave the door open, heat is merely recycled from the room into the refrigerator, then back into the room. A net room temperature increase would result from the heat of the motor that would be constantly running to move energy around in a circle.
