Correct option is B
An emergency evacuation plan is designed to ensure that all individuals can exit a workplace safely and systematically during emergencies such as fire, gas leaks, or structural hazards. It includes defined escape routes, assembly points, and assigned responsibilities to avoid panic and confusion.
The primary aim is safety of human life, not productivity or cost reduction. Options a, c, and d are incorrect because they do not relate to emergency preparedness. In fact, safety drills and evacuation plans are essential to reduce risks and improve response time.
