Final answer:
For a graphic design workstation, the essential components include a discrete graphics card and dual monitors, which aid in rendering tasks and efficient multitasking. Items like high-quality speakers or a barcode scanner may enhance the experience but are not considered essential for graphic design purposes.
Step-by-step explanation:
When building a graphic design workstation, the essential components you need to focus on are heavily related to the performance and quality of the visualization aspects of your projects. The correct answer to the question would be c) Discrete graphics card and dual monitors. A discrete graphics card will provide the processing power necessary for graphic design tasks, such as 3D rendering or high-resolution video editing. Dual monitors offer the ability to have an extended desktop, which is valuable for multitasking and having multiple applications open concurrently for an efficient workflow.
Regarding the other options, a mechanical keyboard and a projector may enhance your experience, but are not essential. High-quality speakers and a gaming mouse could be good for entertainment or certain interactive tasks, but they aren't core graphic design needs. A barcode scanner and 3D printer are specialized tools that would only be necessary for specific design tasks.
