View answer and explanation
Correct option: A
Both (A) and (R) are true and (R) is the correct explanation of (A)
Option A (Both (A) and (R) are true and (R) is the correct explanation of (A)) is correct because a refrigerator transfers heat from a cold reservoir to a hot reservoir, requiring work, and opening it in a closed room will eventually heat the room.
