Which component of scientific inquiry involves proposing a tentative explanation that can be tested through experiments?

• A. Theory
• B. Inductive Reasoning
• C. Hypothesis
• D. Controlled Experiment

Answer: (C)

Forming a hypothesis means proposing a tentative explanation that can be tested through experiments. A hypothesis is a specific, testable statement about how one variable affects another, and it should be falsifiable—that is, there must be a possible result that could prove it wrong. In practice, you design experiments to test the prediction the hypothesis makes, by changing the independent variable, observing the dependent variable, and controlling other factors so that any observed effect can be attributed to the tested relationship. Depending on the results, the hypothesis is supported, refuted, or revised, and further testing may follow.

This differs from a theory, which is a broad, well-supported framework built from many tested hypotheses and observations; from inductive reasoning, which is the general process of drawing broad conclusions from specific observations; and from a controlled experiment, which is a method used to test hypotheses rather than the tentative explanation itself.
