What are some applications of industrial robots?

• A. Painting tasks only.
• B. Data collection in labs.
• C. Medical device manufacturing exclusively.
• D. Material handling, processing operations (like welding and cutting), and assembly and inspection.

Answer: (D)

Industrial robots are used on manufacturing lines to handle repetitive, precise, and potentially hazardous work with speed and consistency. The best answer captures the broad range of common tasks: moving and handling materials (loading, unloading, and transferring parts), processing operations (examples include welding and cutting, but also painting, drilling, grinding), and assembling components while also inspecting quality along the way. This set reflects how robots contribute across production—moving parts, performing processing steps, and helping verify that products meet standards.

Other options describe tasks that are too narrow or not representative of typical industrial robot use. Painting tasks alone don’t cover the broader capabilities; data collection in labs isn’t a standard factory application; and manufacturing medical devices exclusively is a narrower niche rather than the general, multi-task role robots play in industry.
