Why does a dead body float in water

  1. Body temperature is zero so like ice it floats

  2. Body after death loses its weight

  3. The weight of the water displaced by dead body is more than the weight of dead body

C Correct answer
Explanation

A dead body floats in water due to buoyancy principle - the weight of water displaced equals the weight of the body when decomposition gases accumulate, making it less dense than water. Body temperature being zero doesn't cause floating (ice floats due to crystal structure), and bodies don't lose weight after death.
