Final answer:
Option D: Arsenic is used in electronics and semiconductors, and while it is involved in the production of components in flat screen monitors, mercury is more commonly associated with the screens' backlighting technologies.
Step-by-step explanation:
Among the materials listed, arsenic is used in the production of electronic and semiconductor devices, which includes components found in flat screen monitors. Flat screen monitors rely on a variety of materials for their construction, and while arsenic is used in electronics, it is not typically highlighted as a key material in the flat screens themselves.
Modern flat screens often use liquid crystals or light-emitting diodes (LEDs) and may contain trace amounts of other materials such as mercury in some backlighting technologies. That said, consumer electronics, including flat screen monitors, have been subject to increasing scrutiny and regulation to reduce or eliminate the use of hazardous materials.
