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.
This is known as Onesky.

Answer & explanation:
Mountains are large formations of land at high altitudes, where conditions are often difficult. For example, cold weather and food shortages.
In the highest areas of the mountains, animals such as vultures, eagles, hawks and other birds of prey usually prevail.
In addition, it is common for the sides of the mountains to be covered with forests. In these areas it is possible to observe the predominance of animals such as moose, goats, sheep, skunks, llamas and lynx. This group has good climbing skills and manages to stay in the side of the mountains and in some high areas (not as high as the previous group).
Meanwhile, in the lower parts of the mountains, where the forest is denser, it is possible to observe the predominance of snakes, wolves, marmots, foxes, etc.
Mussels are molluscans and are freshwater animals. The change in the environment led to new traits of mussels, it underwent natural selection and the thick shells have high chances of survival.
<h3>What is natural selection?</h3>
Natural selection is a process of nature that eliminates the organism with less survival and unfit traits while selecting the organisms with better traits of survival in the altered conditions.
The arrival or the introduction of the crabs in the environment altered the previous habitat of the mussels and led to the adaptation of the better trait quality in the mussel species.
The trait of the thick shells underwent natural selection as they were favoured for the changed conditions. The mussel having thick shells have high chances of survival over thin-shelled mussels as the crab will find it hard to attack the thick-shelled mussels.
Therefore, option A. change in environment, option B. natural selection and option E. chances of survival are the correct statements.
