  1. Rotten egg will float but fresh does not

  2. Fresh egg float but rotten does not

  3. Rotten egg shell ruptured

  4. Fresh egg shell ruptured

Show answer
Correct Option: A
Explanation:
The kept secrete in determining an Egg's freshness is to see if it sinks in water. If the Eggs shrink into the bottom and lay flat on their side, they are still
fresh. However, if they sink, but stand on one end at the bottom of the glass or bowl they are not as fresh but still edible. Floating is indeed a sign of less-than-fresh Eggs, but the size of the air pocket is determined by evaporation of moisture from the egg. Evaporation isn't desirable but it's not the same as spoilage. Thus of course if any Egg float to the top they shouldn't be eaten. The science behind this is based on the fact that Eggshells are semipermeable, which means air can get through.
