Recorded observations

• A. Data
• B. Hypothesis
• C. Prediction
• D. Theory

Answer: (A)

Recording observations is about collecting data—the actual measurements and descriptive notes you gather from experiments or fieldwork. Data are the concrete evidence you can analyze to see if a hypothesis is supported. A hypothesis is a testable statement or educated guess about how the system works. A prediction is what you expect to happen in a specific situation if the hypothesis is true. A theory is a well-supported, broad explanation that integrates many verified observations. So when you hear “recorded observations,” the best fit is data—the recorded measurements and observations themselves. For example, recording plant heights after different light treatments yields data; the hypothesis might be that light increases growth, the prediction would be that more light yields taller plants, and the theory would be a broader explanation of plant growth across contexts.
