## **Core Concept**
Contributory negligence is a legal concept in tort law that refers to a situation where the plaintiff's own actions have contributed to the harm or injury they have suffered. In the context of medical negligence, it implies that the patient's own negligence or failure to follow medical advice contributed to the adverse outcome.

## **Why the Correct Answer is Right**
Contributory negligence is a principle that can reduce or eliminate the liability of the defendant (in this case, a healthcare provider) if it is found that the plaintiff (patient) failed to exercise reasonable care, thereby contributing to their own injury. This concept is crucial in medical malpractice cases as it assesses the degree to which the patient's actions (or inactions) played a role in the adverse outcome. By considering contributory negligence, courts can allocate fault and damages accordingly.
