Option C is the correct answer. Osmosis is the process of balancing ion concentration by the movement of fluid through a semi-permeable membrane.
Osmosis can be defined as the process of balancing the concentration of Ions from a Higher concentration to a lower concentration by the movement of a fluid through a semipermeable membrane. This process basically balances out the concentration of the ions where the concentration is lower.
Osmosis is responsible for balancing the concentration of ions from a region where the concentration is higher and the ions move from the higher concentration region to the lower. This makes sure that the environment is in a state of equilibrium.
Hence, Option C is the correct answer.
