Which statement best describes deductive reasoning?

• A. It infers general conclusions from specific observations
• B. It derives specific predictions from general principles
• C. It uses data to form hypotheses
• D. It relies on chance rather than logic

Answer: (B)

Deductive reasoning moves from a general principle to a specific conclusion about a case. You start with a rule that applies to all cases, and then apply it to the particular situation to predict or conclude something definite. For example, if the general principle is that all mammals have backbones, and you know this animal is a mammal, you can deduce that it has a backbone. If the premises are true and the reasoning is valid, the conclusion follows with certainty. This is why the statement describing deductive reasoning as deriving specific predictions from general principles is the best fit: it captures the flow from a broad rule to a particular result. The other options describe different approaches—inductive reasoning builds generalities from specific observations, using data to form hypotheses is about generating ideas to test, and relying on chance isn’t a logical method at all.
