Explanation

• The correct sequence of biological method is: Hypothesis → Reasoning → Theory → Law

This sequence represents the scientific method in biology, which involves:

• Formulating a hypothesis (a educated guess) to explain a phenomenon
• Using reasoning and logic to develop predictions and test the hypothesis
• Developing a theory (a well-substantiated explanation) based on the results of experiments and observations
• Establishing a law (a universal principle) that describes the phenomenon
