Best answer
Right choice is (a) Stack

Explanation: Ventilation arising from the temperature difference between outside and inside takes place due to the stack effect. When the temperature of the inside air is higher than the outside air, warmer air passes through the opening situated in the upper part of the room while the cooler air enters the room via the lower openings.
