• A. Reasonable person test
• B. But-for rule
• C. Foreseeability rule
• D. Intervening act

Answer: (A)

The reasonable person standard guides the level of care expected in a situation by asking what a reasonably cautious person would or would not do under similar circumstances. It serves as the benchmark for judging negligence—comparing the defendant’s conduct to how an ordinary prudent person would act to avoid harm. The standard can be adjusted for factors like physical limitations or professional expertise, so a professional is measured against what a reasonably prudent professional would do, and a person with a disability is assessed against what a reasonably cautious person with that disability would do. The other ideas describe causation or how liability can be affected by other factors: the but-for rule addresses whether the injury would not have occurred but for the defendant’s conduct; foreseeability concerns whether the risk should have been anticipated; and an intervening act concerns whether another event breaks the causal link.
