• D. Kerosene lamp - Blue

Answer 1

The correct option is C Kerosene lamp - Yellow

LPG stove - Blue
When kerosene is burned in a lamp, it burns with a yellow flame. The yellow flame is caused by the glow of hot unburnt carbon particles produced due to incomplete combustion. In LPG stove, the LPG burns with a blue flame. The design of the burner of kitchen gas stove is such that it provides sufficient oxygen for the complete combustion of LPG. Hence, due to complete combustion of LPG, it burns with a blue flame.
