Final answer:
The four elements required to establish negligence are Duty, Breach of Duty, Causation, and Damages. To prove negligence, one must demonstrate a legal duty existed, that duty was breached, the breach caused harm, and actual damages resulted.
Step-by-step explanation:
The four things needed to establish negligence in a legal context are: Duty, Breach of Duty, Causation, and Damages. This means that for someone to be found negligent, it must be shown that they had a legal duty to act in a certain way, they breached that duty by acting or failing to act, their breach caused injury or harm (causation), and the injured party suffered actual damages or losses as a result. Therefore, the correct answer is option 1: Duty, Breach of Duty, Causation, Damages.
