Answer: (A)

Industrial hygiene is the proactive discipline that protects workers by identifying and controlling hazards before they cause health problems. The best choice defines it as the science and art of anticipating, recognizing, evaluating, and controlling workplace conditions to prevent adverse health effects. This emphasizes not just reacting to problems, but foreseeing hazards (like chemicals, noise, heat, or dust), assessing exposures, and applying controls to keep health risks low. It also covers a range of strategies—engineering controls (ventilation, enclosure), administrative controls (work practices, shift rotation), and personal protective equipment used when other controls aren’t enough. It’s broader than just ensuring environmental compliance or improving production efficiency, and it isn’t limited to the use of protective clothing.
