The correct option is B Convection
The phenomenon involved here is convection. Convection occurs when particles with heat energy in fluids move and replace particles with comparatively lesser heat energy.
Human beings give out carbon dioxide which increases the CO2 content in the room, which makes the air warmer. The moist, warm air containing carbon dioxide becomes lighter, and hence, rises up. This air then passes out through ventilators which causes a drop in pressure within the room. Thus, the cold and fresh air from outside enters in through the doors and windows.
This continuous circulation of air is maintained within the room by the phenomenon of convection.
