Final answer:
Nikola Tesla's work with AC power distribution contributed to bringing electric power to buildings, including the chandeliers in the White House, by enabling electricity to reach greater distances.
Step-by-step explanation:
Nikola Tesla's work on the development of the AC (alternating current) system for the Westinghouse Electric & Manufacturing Company greatly influenced the way electricity was distributed, allowing it to reach vast urban areas and power devices such as the chandeliers in the White House. His contributions enabled extended power supplies for lights and other equipment, which could be located miles from the power source. Because of Tesla's AC system, electric lighting became more practical and widespread, transforming factories and urban living by empowering cities to remain illuminated even during the night. Therefore, Tesla's work affected the chandeliers in the East Room of the White House in 1963 by contributing to bringing power to the building (Option 1).
It is important to note that Thomas Edison, not Nikola Tesla, is credited with the invention of the first practical incandescent lightbulb, and it was Edison's laboratory that developed the system of dynamos and wiring for electric bulbs. However, the technology ultimately used to produce and distribute electricity worldwide was AC power, as developed by Tesla and Westinghouse, despite Edison's earlier attempts with DC (direct current).
