Step-by-step explanation:
The correct answer to the question is a) Regulatory agency.
The regulatory agency has authority to stop, alter, or suspend activities that present an imminent threat of harm. In the legal system, regulatory agencies are created by legislative bodies to implement and enforce laws. These agencies have the power to issue rules and regulations that govern specific industries or activities, and they can take action to protect public safety and welfare.
For example, the U.S. Environmental Protection Agency (EPA) is a regulatory agency that has the authority to regulate and enforce laws related to environmental protection. If the EPA determines that an activity or industry is causing harm to the environment, it can take action to stop or mitigate that harm.
