Answer:

D) passive transport

Explanation:

Passive transport is the movements of molecules or ions from the region of its higher concentration to its lower concentration or along the concentration gradient. Since passive transport occurs along the concentration gradient, no energy input is required in the process. An example of passive transport is simple diffusion or facilitated diffusion.

Substances like oxygen pass through the cell without the use of energy and move from an area of high concentration to an area of low concentration that occurs during passive transport.

Further Explanation:

Every molecules that passes across the cell has to cross the cell membrane barrier. The cell membrane is mainly made up of lipid bilayer which allows the hydrophobic molecules to pass throughit and restricts the entrance of hydrophilic molecules. It also allows the uncharged molecules to pass through the cell by simple diffusionand restricts the passage of charged molecules.

There occurs two basic type of transport-

Passive transport
Active transport

Passive transport is the type of transport wherein energy is not required for movement of molecules across the cell. During this type of transport the molecules moves from high concentration gradient to low concentration gradient.

The oxygen is an uncharged molecule that can easily pass through the cell from high concentration to low concentration without the expenditure of energy. In the active transport the molecules moves from low concentration gradient to high concentration gradient which requires energy in the form of ATP.

Osmosis is specifically used for the transport of water molecule from high concentration to low concentration gradient.
