Final answer:
Grant's law was established to reduce the risk of violence for gas station attendants following the death of Grant De Patie. It mandates prepayment for fuel as a safety measure and does not directly concern social workers or other elements of workplace violence.
Step-by-step explanation:
Grant's law was created to reduce the risk of violence for gas station attendants. The tragic death of a gas station attendant named Grant De Patie in British Columbia, who died trying to prevent a gas-and-dash incident, led to the establishment of the legislation. This law requires prepayment for fuel at gas stations to protect attendants from robbery and violence. It does not pertain to health insurance acquisition, healthcare costs reduction, or employment in the healthcare industry, as referenced by the incorrect options B, C, and D provided. Grant's law is specifically designed as a crime prevention measure, thereby increasing the safety of workers in this industry. While the law provides safety benefits to these attendants, it does not directly impact social workers or the broader scope of workplace violence beyond the domain of gas stations.
