Materials that allow water to pass through them easily are
a. permeable.
b. impermeable.
c. saturated.
d. unsaturated

permeable

Explanation:

Permeable: Materials which allow water to pass through them. Example: Sand

Impermeable: Materials which do not allow water to pass through them. Example: Clay

Saturated: Solutions in which no more solute can be added to the solution at that particular temperature. Example: When sugar can be seen in the water

Unsaturated: Solutions which contain less than the maximum amount of solute that can be present at that temperature. Example: When sugar completely dissolves in water.
