Answer: (B)

Verified step by step guidance

1. Understand the definition of a biological theory: A biological theory is a well-supported explanation of natural phenomena that is based on a large body of evidence collected through observation, experimentation, and analysis.
2. Eliminate options that do not align with the scientific method: Anecdotal stories, unproven personal opinions, and random guesses without experimentation are not considered valid scientific evidence because they lack systematic investigation and reproducibility.
3. Focus on the correct option: Well-supported explanations based on evidence are the foundation of biological theories. These explanations are derived from rigorous testing, peer review, and consistent results across multiple studies.
4. Consider the role of evidence in science: Evidence must be objective, measurable, and reproducible. This ensures that biological theories are reliable and can be used to predict and explain phenomena in the natural world.
5. Conclude that biological theories are built on a framework of evidence and scientific reasoning, distinguishing them from anecdotal or subjective claims.
