Answer 2

smell of a burning insence stick will reach to us by the process of diffusion.

Explanation:

matters have different inter molicular space according to their physical nature i.e.,

(1) in solid state - presence of negligible or no inter molicular space.

(2) in liquid states - presence of less inter molicular space.

(3)in gageous state - presence of huge inter molicular space as compared to solids or liquids.

this is the only reason of why the the smell of burning insence stick reaches us.

other examples of diffusion - (1) spreading of perfure in the air throughout the room

(2) smell of being cooked something

(3) diffusion of colours throughout the water ,etc .
