It is hotter at some distance over the flames than in front of it because :

Aair conducts heat upwards only
Bheat is radiated upwards only
Cconvection of heat occurs upwards only
Correct Answer
Dheat is radiated downwards only

Solution

Near flames, heat transfer occurs by both convection and radiation (and some conduction too).
But convection occurs only in upward direction. So, above the flame, it is hotter rather than in front of the flame.
