Answer:
The correct answer is letter "A": assumption of risk .
Explanation:
In Law, assumption of risk is a doctrine in which an individual can be denied the coverage of damages when the harm was caused because of an object that the individual knew could cause harm but used willingly. An example of this doctrine is applied when people enter an area where there is a risk of injury due to ongoing constructions without any protective gear and where signs are indicating the danger. Under the assumption of risk, the company in charge of the work would not be liable for the individual's negligence.
