While cooking if base of the vessel is darkened outwards it implies that fuel is not completely consumed.
At the point when fuel doesn’t consume appropriately,,it starts to form incomplete burning flames/Back flames , that stores on the base of the vessel.
This is called as a “ incomplete combusion “
Hence beacuse of this there will be blackened colour outside of the vessel.
 
Correct option (B) : The fuel is not burning completely.
