**Why the Correct Answer is Right**
Ergonomics is crucial in medical settings, particularly in the operating room, to prevent musculoskeletal disorders and reduce the risk of injury to healthcare workers. Proper ergonomic design of workstations, equipment, and tools can minimize physical strain and improve productivity. This involves considering factors such as posture, movement, and workload to create a safe and comfortable working environment.
**Why Each Wrong Option is Incorrect**

**Option C:** This option is incorrect because it is not a recognized principle of ergonomics, and it does not contribute to the understanding of the subject.
**Clinical Pearl / High-Yield Fact**
A key principle of ergonomics is to design workstations and equipment to accommodate the natural range of motion of the human body, reducing the risk of injury and improving overall comfort.
