Correct option is D
Impairment is generally considered a biological condition, referring to any loss or abnormality of psychological, physiological, or anatomical structure or function. This definition encompasses all forms of physical and mental impairments. On the other hand, disability is often viewed as a functional condition, indicating a restriction or lack of ability to perform an activity in the manner or within the range considered normal for a human being. This distinction emphasizes that while impairments can be directly related to bodily functions, disabilities are about the impact those impairments have on functioning in society.
Information Booster:
(a) Functional, biological would inaccurately imply that impairments are more about functionality rather than biological aspects, which is the opposite of the accurate distinction.
(b) Operative, physical and (c) social, psychological do not correctly align with the standard definitions used in health and disability studies, which see impairments as rooted in biology and disabilities as the functional consequences within the social and environmental context.
