The correct option is B. Electrogenic pumps creates a voltage difference across the membrane.

Explanation:

Electrogenic pumps are used to travel molecules in and out of a cell by establishing a concentration gradient. Hence, the statement that best describes the property of electrogenic pumps is B.

Other options, like option A is correct but it does not describe the general property of the electrogenic pump. Option C is incorrect because not a large variety of solutes can pass through the membrane.
