All but one is a method of passive transport in cells. a. osmosis b. sodium / potassium pump c. facilitated transport

The correct answer will be option-A

Explanation:

The transport of the molecules between cells and a cell and its surrounding is very important to survive.

A cell has evolved two ways to transport the molecules which are passive and active movement or transport.

The passive movement is the movement of the molecules across the membrane depending on the concentration gradient without using any source of energy which is utilized in active transport.

In the given question, osmosis is the process which can be considered passive movement as it transports the water down the concentration gradient without using any source of water.

Thus, osmosis is the correct answer.
