Mummification as a form of delayed postmortem change occurs under which specific environmental conditions, and the minimum time for complete mummification of an adult body in favourable conditions is approximately:

• A Hot, dry, well-ventilated conditions; minimum 3 months ✓
• B Cold, moist, poorly ventilated conditions; minimum 1 year
• C Submerged in cold freshwater; minimum 6 months
• D Buried in clay soil below 2 metres depth; minimum 2 years

Explanation

Mummification (desiccation) requires hot, dry, well-ventilated conditions that dehydrate tissues faster than bacterial putrefaction can proceed. Low humidity removes moisture from surface tissues, creating a hard, dry, parchment-like covering that inhibits bacterial growth. Complete mummification of an adult body typically requires approximately 3 months in ideal conditions (desert, hot attic, arid climate). Adipocere, the other post-putrefactive delayed change, occurs in opposite conditions — moist, warm, anaerobic (waterlogged soil or submerged bodies). Cold freshwater leads to adipocere formation, not mummification.
