The correct answer is descriptive, because the scientists are writing down observations but not making comparisons
Descriptive method is one of the classifications of scientific research, in which its objective is to describe the characteristics of a population, a phenomenon or experience for the study carried out.
It is carried out taking into account the aspects of the formulation of the questions that guide the research, in addition to establishing a relationship between the variables proposed in the object of study under analysis.
In descriptive research, it is up to the researcher to study, analyze, record and interpret the facts of the physical world, without manipulating or interfering with it. He must only discover the frequency with which the phenomenon occurs or how it is structured within a given system, method, process or operational reality.
