Which statement about a hypothesis is most accurate?

• A. It is a proven fact
• B. It is an untestable belief
• C. It is a tentative, testable explanation
• D. It is a tentative, testable explanation or educated guess

Answer: (D)

A hypothesis is a starting point for investigation: a tentative, testable explanation for a question or observation. It’s a reasoned guess about how two or more things relate, and it’s something you can test through experiments or careful observation. It’s not a proven fact, because science builds knowledge by testing ideas and seeing what the evidence shows. It’s also not an untestable belief; a good hypothesis makes predictions that you can confirm or disprove with data. The strongest description is that a hypothesis is a tentative, testable explanation or educated guess—based on what you know, yet still waiting to be confirmed or revised through testing. For example, you might hypothesize that increasing sunlight will boost a plant’s growth. This makes a clear prediction you can test by comparing plant growth under different light conditions.
