The correct answer is Fungi growing in soils of burnt terrains.
‘Pyrophilous’ means ‘fire-loving’. Pyrophilous organisms are those that are either dependent on fire for part of their life cycle or thrive in environments recently affected by fire. Fungi that specifically colonize or grow best on burnt organic matter or in fire-affected soil are classic examples of pyrophilous organisms.
While fresh grass might grow rapidly after a fire (due to nutrient release and reduced competition), the term pyrophilous specifically describes organisms that are *favored* *by* the fire itself. Some seeds are pyrophilous because heat from fire breaks dormancy. Option D describes regeneration after injury, not fire dependency.
