Answer:
c. breach of duty
Step-by-step explanation:
A duty of care is a legal obligation that a person has when he is conducting acts that could harm others. This is a duty to be reasonably careful when caring for others. Duty of care is a particularly important concept as it is the first factor that needs to be discussed when proceeding with an action in negligence. A violation of this duty is called breach of duty. If a person has breached this duty, he or she might be subject to liability.
