Answer:
B. The natural world should be disturbed as little as possible in an experiment
Explanation:
In doing any type of experiment that includes the natural world, the best and most ethical way to do it is to make as little disturbance to it as possible. The reasons for this are many. One of them is that if the experiment creates big disturbance to the natural world, it will create lot of damage to it, with many species becoming endangered or extinct. Also, the natural world is needed, both for the humans and for having proper living conditions for the other organisms. The ethical part also plays big role, as to perform an experiment with the cost of harming millions of organisms is very cruel and irresponsible, plus there's not a single positive in it.
