b. False

True

Explanation:

Diffusion is the movement of the particles of a substances from a region of higher concentration to a region of lower concentration.

Diffusion occurs in response to a concentration gradient.

In this case, the dye is at a higher concentration at the middle of the shallow dish of water. Diffusion causes the dye to spread out gradually thereby causing the red cloud to grow larger with time.
