The correct answer is B.
The transmissibility of an aquifer is a measure of its ability to transmit water. It is defined as the product of the permeability of the aquifer and the saturated thickness of the aquifer. The saturated thickness is the depth of the aquifer that is filled with water.
The permeability of an aquifer is a measure of how easily water can flow through the aquifer. It is a measure of the ability of the aquifer to transmit water.
The relationship between permeability and transmissibility is given by the following equation:
$${\text{T}} = \frac{{\text{k}}}{{\text{d}}}$$
where:
- T is the transmissibility of the aquifer
- k is the permeability of the aquifer
- d is the saturated thickness of the aquifer
Therefore, the correct answer is B.
