Solution

The correct option is D both A and B are true
Conduction and convection are processes where heat is transferred by the collision of molecules. Hence, for these processes to take place, we need a material medium.
In radiation, heat travels as electromagnetic waves which do not require a medium to travel. Its transfer mechanism is completely independent of the medium.
