Porosity
The measure of how much of a rock is open space, which could be filled by liquids or gases.
Igneous Rocks
Geological formations that originate from the solidification and cooling of molten rock materials.

Final Answer :
E
Explanation :
All the statements provided are valid regarding porosity. Porosity does indeed depend on the amount of water that can be stored, is influenced by the size and shape of grains and clasts, is higher in better sorted sediments compared to unsorted ones, and in some igneous rocks, fractures may indeed be the only significant source of porosity.
