Solution

The correct option is B
Decomposition reaction

On heating potassium chlorate ( $K C l O_{3}$ ) it gives potassium chloride (KCl) and oxygen. This reaction can be represented as:

$2 K C l O_{3} \to 2 K C l + 3 O_{2}$

Potassium chlorate ( $K C l O_{3}$ ) decomposes into potassium chloride (KCl) and oxygen on application of heat therefore this is decomposition reaction.
