Step-by-step explanation:
The process of evaluating the level of safety in operation is typically referred to as a safety audit. A safety audit is an examination and assessment of all or part of an organization's operations and processes, specifically regarding safety protocols and compliance with safety regulations. This type of audit is intended to ensure that workplace practices conform to established safety standards and to identify areas where improvements can be made. The correct answer to the student's question is “C. Safety Audit.”
Risk analysis is often part of the broader process of a safety audit, but it specifically involves examining potential risks to determine their impact and develop strategies to manage them. An emergency drill is a practice session for preparation in the event of an emergency, such as a fire or natural disaster. However, it is not the formal process to judge the level of safety in operation, which is best done through a safety audit.
