A permeable layer of sediment or rock that allows water to flow through is called
A
aquitard
B
aquifer
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -An aquifer is a body of porous rock or sediment saturated with groundwater. Groundwater enters an aquifer as precipitation seeps through the soil. It can move through the aquifer and resurface through springs and wells.

Detailed explanation-2: -Permeability is a measure of the interconnectedness of pores. The connection between pore spaces allows groundwater to flow through the sediment or rock. The combination of water storage (porosity) and flow (permeability) makes a good aquifer-a rock unit or sediment that contains usable groundwater.

Detailed explanation-3: -An aquifer is a body of saturated rock through which water can easily move. Aquifers must be both permeable and porous and include such rock types as sandstone, conglomerate, fractured limestone and unconsolidated sand and gravel.

Detailed explanation-4: -Porous/permeable layers are called aquifers; impermeable layers called aquicludes.

Detailed explanation-5: -Groundwater is water that exists underground in saturated zones beneath the land surface. The upper surface of the saturated zone is called the water table.
