None of these
A
Correct answer
Explanation
Burning kerosene oil is classified as rapid combustion because it occurs at a fast rate when the fuel is ignited, producing heat and light steadily. Option A correctly identifies this as rapid combustion. Spontaneous combustion (B) occurs without external ignition. Explosion (C) involves sudden, violent combustion with pressure waves. Kerosene burning is a controlled, steady burning process, not an explosion.
