Answer: C. An idea that is supported by many different experiments
Step-by-step explanation:
A scientific theory is a well-substantiated explanation of some aspect of the natural world that is based on a body of evidence gathered through experimentation and observation. It goes beyond a single hypothesis and is supported by multiple lines of evidence from various experiments and observations. A scientific theory is more than just an educated guess or a single scientist's conclusion; it's a comprehensive framework that has withstood rigorous testing and scrutiny.
