Solution

The correct option is D
Assertion:- True

Reason:- False

Incense stick has the fragrance but it spreads in the room only when the incense stick is lit. As we lit the incense stick the temperature of incense stick is raised which further increases the kinetic energy (energy associated in the motion of particles) increases. Incense stick on raising the temperature converts from solid to gas state and particles having higher kinetic energy starts to diffuse (intermix) more into the room. So the assertion is TRUE and the reason is FALSE.
