Which term refers to a physical or mental condition that limits an individual's abilities?

The term that refers to a physical or mental condition that limits an individual's abilities is "disability." This term encompasses a wide range of conditions that can affect a person's movement, senses, cognition, or overall functioning. A disability may be ongoing or temporary and can affect daily activities and participation in society.

Other terms listed have different implications. "Incapacity" often refers to a state of being unable to act or respond due to a mental or physical condition, but it doesn't necessarily imply a condition affecting abilities in the same comprehensive manner as disability does. "Restriction" refers to limitations imposed on a person but doesn't specifically denote a condition. "Impairment," while closely related to disability, generally focuses on the loss of normal function, such as mobility or vision, but it doesn’t capture the broader impact that disabilities have on a person's abilities in society.
