The best statement that explains why the room starts to feel cooler when the teacher opens a window on a cold day is:
**A) Air moves from areas of higher temperature to areas of lower temperature.**
This statement reflects the principle of heat transfer, where warmer air inside the room will mix with the cooler air coming in from outside, leading to a drop in the overall temperature inside the room. While statement D also highlights that cold air is coming into the room, statement A more broadly explains the mechanism of temperature change in the room.
