  1. Digested state

  2. Liquid state

  3. Semisolid state

  4. Solid state

Show answer
Correct Option: B
Explanation:
Once a housefly sniffs something interesting and tastes it with its feet and palps, the time has come to gobble up the delicious morsel. If the meal in question happens to be liquid already, then the task is easy. Since the housefly's mouth parts are designed to sponge and ingest liquefied food, it's just a matter of turning on the suction. The food goes straight into the fly's stomach. Solid food is slightly more difficult. Houseflies can't bite or chew -- they simply don't have the proper equipment.

So, the correct answer is 'Liquid state'.
