The best option is B. Places a physical barrier between the worker and machine.
Explanation: Guards are safety devices designed to prevent accidental contact between workers and hazardous machinery. By creating physical barriers, they effectively protect workers from potential injuries that could occur if a worker were to reach into the machine while it is operating. This is a critical safety measure in workplaces involving heavy machinery.
