C

Explanation:
The “reasonable person” standard in tort law is an objective benchmark assessing how a hypothetical reasonable person would act in similar circumstances. For individuals with physical disabilities, the standard adjusts to account for their condition, requiring them to act as a reasonable person with the same disability would. Option C is correct. Option A is incorrect because the standard is objective, not subjective to each person. Option B is incorrect because the standard focuses on behavior, not mental state. Option D is incorrect because mental disabilities typically do not alter the objective standard, as courts hold individuals to the general reasonable person standard unless the disability is severe and relevant.
