Specific retention as the word itself says that how much water can be stored in a rock against the gravity. And in coarse gravel the size of voids is so large that it can't store water in it. Therefore the Sr for CG is least and more for clay.

Yes sir, your reason is absolutely correct, thank you @Thanveer.

Because of more porosity and voids in the gravel, so water will pass through it quickly without as compare with others.

The above reason is wrong porosity, and voids are more in case of clay.

The Specific Retention (SR) of a rock or soil is the ratio of the volume of water.
A rock can retain against gravity to the total volume of the rock.
A rock can retain against gravity to the total volume of the rock.

Voids are more in gravel but porosity is more on clay.

Well said @Thanveer.

Is porosity and permeability are inversely proportional?

Clay is the answer here because rack can't retend water.
