The chimney draught varies with:.
Climatic conditions: Changes in atmospheric pressure and temperature can affect the density of air, which influences the draught.
Temperature of furnace gases: Hotter gases are less dense and rise faster, increasing the draught.
Height of the chimney: A taller chimney creates a stronger natural draught due to the greater pressure difference between the base and the top of the chimney.
So, the correct answer is all of these.
