Concept:A wick draws liquid upward through narrow spaces between its fibres.Explanation:Kerosine moves through the tiny gaps in the wick because of capillary action.Capillary action is the ability of a liquid to flow in narrow spaces without external help, due to adhesion and surface tension.This is why kerosine travels along the wick, not by diffusion, suction, or osmosis.Answer:C. capillary action.
