This example of passive transport occurs in water molecules
A
facilitated diffusion
B
difussion
C
simple diffusion
D
osmosis
Explanation: 

Detailed explanation-1: -Osmosis is a form of passive transport when water molecules move from low solute concentration(high water concentration) to high solute or low water concentration across a membrane that is not permeable to the solute. There is a form of passive transport called facilitated diffusion.

Detailed explanation-2: -Water, which can quickly pass through the membrane via channel proteins, will begin to leave the cell at a higher rate than it enters, with a net movement to the area with a high concentration of A, thus lowering the concentration. This is an example of osmosis.

Detailed explanation-3: -Some materials, like water and oxygen, can enter and leave cells without the cell needing to expend any energy. This is passive transport. Passive transport usually occurs down a concentration gradient.

Detailed explanation-4: -Examples Of Passive Transport Reabsorption of nutrients by the intestines by separating them from the solid waste and transporting the nutrients through the intestinal membrane into the bloodstream. When a raisin is soaked in water the water moves inside the raisin by the process of osmosis and it swells.
