Verified step by step guidance

Understand the definition of a scientific theory: A scientific theory is a comprehensive explanation of some aspect of the natural world that is supported by a large body of evidence and has been repeatedly tested and confirmed through observation and experimentation.

Differentiate between a scientific theory and other scientific terms: A scientific theory is not just a collection of observations, nor is it an educated guess or a hypothesis proven by a single experiment.

Recognize the characteristics of a scientific theory: It is well-substantiated, based on a body of evidence, and has stood the test of time through repeated testing and validation.

Evaluate the options given in the problem: Compare each option to the characteristics of a scientific theory to determine which one fits the description best.

Select the correct option: Choose the option that accurately describes a scientific theory as a well-substantiated explanation based on evidence and time-tested validation.
