Answer 3

[AI-generated answer — Explain Bot]

The correct answer is b) diffusion. Diffusion is the passive movement of particles from an area of higher concentration to an area of lower concentration, without the use of energy or membrane proteins. It is driven by the random motion of particles and the goal to achieve equal distribution or equilibrium. The process of diffusion does not require any specific channels or carriers for the movement of the substance, which distinguishes it from facilitated diffusion (option a), endocytosis (option c), and the sodium-potassium pumps (option d).
