C. kinetic energy
On a microscopic scale, conduction occurs as rapidly moving or vibrating atoms and molecules interact with neighboring particles, transferring some of their kinetic energy.

Answer:
The correct option is A. Diffusion
Explanation:
Diffusion can be described as a mechanism through which molecules move along the concentration gradient i.e from an area of higher concentration to an area of lower concentration. This process does not require energy as the molecules or ions move along the concentration gradient.
Hence, the pumping excess sodium ions by the cell membrane to an area where the concentration of sodium is less would be an example of diffusion.
