D. descriptive investigations
Explanation:
A scientist studying the star Alpha Centauri would probably rely on descriptive investigation to gather data.
In descriptive investigation, experiments cannot be performed since the subjects cannot easily be manipulated or they are far too inaccessible. This form of investigation is based on indirect qualitative investigation of a phenomenon.
- Alpha Centauri is a distant star several light years away from the vicinity of the scientist.
- The best way to investigate this distance body is to make inferences from the evidence gathered from observatory stations using telescopes.
- Astronomers can collect different information and give vivid description of the distant start.
- It is highly impossible to make comparisons and alter variable in this kind of investigation.
