Question

what is a theory? an assumption made about an experiment an untested guess as to how something might work a generally accepted, well - tested explanation as to why something occurs

Explanation:

To determine the correct definition of a theory, we analyze each option:

• The first option describes a hypothesis (an assumption for an experiment), not a theory.
• The second option defines a hypothesis (an untested guess), not a theory.
• The third option matches the scientific definition of a theory: a well - tested, generally accepted explanation for why a phenomenon occurs.

Answer:

C. a generally accepted, well - tested explanation as to why something occurs (assuming the options are labeled A, B, C in order from top to bottom)
