In which condition is fossil formation more likely?
Answer and explanation
Correct answer: When remains are quickly covered by sediment
Fossilisation requires preservation of remains for a long period. Rapid burial by mud, sand, or other sediment can protect remains from oxygen, scavengers, weathering, and physical damage, reducing decomposition. Hard parts such as bones and shells are especially likely to persist. Quick decay, burning, or prolonged exposure destroys evidence, so option B gives the most suitable condition.
