Concept:Permeability describes whether water can pass through a rock.
A rock that blocks the flow of water is called impermeable.
Explanation:Permeable rocks allow water to pass through easily because they have connected openings.
Porous rocks contain holes or pores, but these pores may not be connected enough to let water flow through.
Sedimentary rocks are formed by the deposition and compression of sediments over time.
Impermeable rocks do not allow water to pass through easily.
This means water cannot flow through them quickly or at all.
Hence, the rock described in the question must be impermeable.
Answer:D. impermeable
