Step-by-step explanation:
The answer to the question is a) scientific method. Scientists develop an understanding of the natural world according to a set of guidelines known as the scientific method. The scientific method involves making observations, forming hypotheses, conducting experiments, and drawing conclusions based on evidence and logic.
It is a systematic and logical approach used by scientists to investigate and understand the natural world. For example, if a scientist is studying the effects of temperature on plant growth, they would observe the plants at different temperatures, form a hypothesis about how temperature affects plant growth, conduct experiments to test their hypothesis, and then analyze the results to conclude.
