Explanation:
The hot air is less dense (lighter) than the cooler air around it, so it naturally goes upward, making the area above the flame hotter than the area to the sides of it.
On the side of the fire you’re only getting the radiant heat from the burn. On the top you are getting the convective hot air and actual burn chemicals (smoke, etc.) rising with the less dense air.
Hence the D option is correct .

The hand above the flame gets more heat due to convection. On the sides, there is no convection and so air does not feel as hot as at the top.❤️
