Here are the essential concepts you must grasp in order to answer the question correctly.
Semipermeable Membrane
A semipermeable membrane is a barrier that allows certain molecules or ions to pass through while blocking others. In biological systems, this property is crucial for maintaining homeostasis, as it regulates the movement of substances between compartments, such as cells and their environment.

Osmosis
Osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. This process continues until equilibrium is reached, which is essential for maintaining proper cell function and volume.

Concentration Gradient
A concentration gradient refers to the difference in the concentration of a substance across a space. In this scenario, the gradient exists between compartments A and B due to differing KCl concentrations, driving the movement of water and ions until the concentrations equalize, illustrating the principles of diffusion and osmosis.
