• A. Appearance of larvae in decaying organic matter
• B. Microbes did not appear in stored meat
• C. Microbes appeared from unsterilized organic matter
• D. Maggots did not appear in the meat, when heated and kept in a sealed vessel

Answer 1

The correct option is D Maggots did not appear in the meat, when heated and kept in a sealed vessel

Francesco Redi, an Italian physician, took flesh and cooked it so that no organisms were left alive. Then he placed three pieces of sterilized flesh in three different jars, of which, one was uncovered, the second was covered with parchment and the third one was covered with fine muslin. He observed that maggots developed after few days only in the uncovered jar through which the flies also visited other jars.
