This question seems to be incomplete because the experiment is not described but it is possible to answer it.
The correct answer is B. Redi disproved spontaneous generation.
Explanation:
Francesco Redi was an important scientist during the 17th century known for his experiments about maggots in rotten meat. This is because during Redi's time it was believed rotten meat was the origin of maggots because maggots seemed to emerge from this. Additionally, this perception was related to the spontaneous generation or the idea life can emerge from non-living materials. The results of this experiment show the idea about spontaneous generation was not true in the case of meat and maggots because maggots were simply the result of eggs flies laid on rotten meat. This means this experiment disproved spontaneous generation.
