Which of the following best describes ergonomics?

Ergonomics is best described as the study of people's efficiency in their working environment. This field focuses on understanding how people interact with their environments and how this interaction can be optimized. It involves designing tasks, workspaces, tools, and equipment that fit the physical and cognitive needs of users to enhance comfort, safety, and performance.

By applying ergonomic principles, designers and employers can reduce the risk of discomfort and injury, enhance productivity, and improve overall well-being. This includes considering factors like body mechanics, posture, and workflow in workplaces to foster a more effective and healthy work environment.

In contrast, the other options relate to different disciplines. Creating visually appealing designs falls under aesthetic or graphic design rather than ergonomics. Analyzing the structural integrity of buildings pertains to architecture or engineering fields. The selection of sustainable materials is relevant to environmental design or sustainability practices, not specifically ergonomics. Thus, the emphasis on efficiency and user-centered design solidifies option B as the most accurate description of ergonomics.
