C. Experimental
Explanation - The cause and effect of a process would be studied in experimental investigations. However, in descriptive studies, relationship between the factors are not studies rather the detail of the process is studied. In comparative investigation, several factors are compared and its effects are analyzed.
In experimental investigations, experiments are carried out based on the hypothesis and then it is validated accordingly. Validation is a must to prove and disprove the hypothesis. Therefore, experimental data and hypothesis are related.
It's some change in the conditions around the organism, which the organism can detect and respond to. A change in temperature, more light, or something physically poking the organism are examples.
When Darwin returned to England aboard the HMS Beagle after his voyage to the Galapagos Islands, he used artificial selection to help gather data to justify his theory of evolution. After studying the finches on the islands, Darwin moved to raising birds, notably pigeons, back home to test his theories.
<h3>What, according to Darwin, is artificial selection?</h3>

They may adjust an organism's properties by choosing which creatures were permitted to reproduce. . Darwin referred to this form of alteration in organisms as artificial selection.
