Q: Kerosene oil rises up in wick of a lantern because of
  • A. Gravitation
  • B. Capillarity
  • C. Diffusion
  • D. Osmosis
Correct Answer: Option B - Kerosene oil rises up in wick of a lantern because of capillary action. If the surface tension of oil is zero, then it will not rise, so oil rises up in a wick of a lantern due to surface tension.
