  • B.ground fire
  • C.creeping fire
  • D.surface fire

Answer: D

The fire is a surface fire.

Forest fires are classified by the layer of fuel they burn. A surface fire runs along the forest floor, burning the litter and ground cover and also the undergrowth, small shrubs and young regeneration, without reaching the canopy. It is the commonest type of forest fire in India.

A ground fire burns slowly within the humus and organic matter below the surface, often without flames. A crown fire spreads through the tree tops. 'Creeping fire' describes the slow spread of a low fire along the floor and is not the standard class for a fire that also burns the undergrowth.
