Final answer:
The deficiency approach does not follow any of the given steps (A, B, or C). Instead, it follows a three-step process involving observing natural phenomena, proposing a hypothesis, and conducting an experiment to gather evidence.
Step-by-step explanation:
- Observe natural phenomena: This involves observing and reading about the science of others to gather information.
- Infer and propose a hypothesis: Based on objective and rational thinking, propose a hypothesis that explains the observed phenomena.
- Design and perform an experiment: Create an experimental setup to test the hypothesis and collect measurable data as evidence.
