to put it in a layman's terms:
conduction is the heat transfer through contact...convection is the heat transfered through mixing and radiation is the heat emitted by a hot body...so the answer was radiation...any science student should have no doubts about it..:P
@Arbab Danish: In reply to your hypothesis
If we were to believe in your hypothesis then the following scenario must be true as well:
it is a sunny day and a cool breeze from the sea is blowing inland...you would not feel as much heat as you would in case it was a sunny day and there was no breeze...so do you suggest that the sun suddenly radiated lesser amount of energy?...When you have a fire in the room, and you turn on a fan, radiation remains there, but its effect is lessened because of (assumingly) cold air that is being thrown at you by the Fan....
secondly energy transfer is not through a single process alone...in most cases there are many modes of transfer...in a room, with a heater on, you receive energy through both convection and radiation and probably conduction too in case you have a fall on the fire
.....in a scenario where you would be directly in front of the fire, the major chunk of energy transfer would be radiation, if you are behind some wall or anything it will be convection...
