Which term describes evidence that involves direct observation and must be seen with the eyes?

• A. Indirect evidence
• B. Atom
• C. Scientific model
• D. Direct evidence

Answer: (D)

Direct evidence is evidence you can observe directly with your senses, especially what you can see with your own eyes. Because the statement specifies that the evidence must be seen, direct evidence best fits: it comes from something observed firsthand rather than inferred from other data. For example, noticing a color change in a reaction or seeing a bruise on skin are direct observations. Indirect evidence, by contrast, relies on clues or effects to support a conclusion rather than showing the phenomenon itself. The other terms—an atom and a scientific model—are not types of evidence you observe directly.
