The correct answer is option B. The less porous the less permeable.
Explanation:
The porosity of a solid is a character that explains how much the space present between the grains of the solid. The rocks with more space in its grain have high porosity.
Permeability is the ability to pass a liquid through itself and it is closely related to the porosity. The more porosity the more permeability and vice verse.
