C Correct answer
Explanation

Kerosene rises up a lamp wick due to capillarity, also known as capillary action. This phenomenon occurs when liquid flows through narrow spaces without external forces, driven by surface tension and adhesive forces between the liquid and solid. Viscosity would slow the movement, while gravitation would pull liquid downward.
