Melting Points for Three Elements in Earth’s Crust, by Tectonic Plate

Earth's crust is primarily composed of several elements, among which silicon, aluminum, and iron are common. The crust is made up of several large pieces of solid rock called tectonic plates. These tectonic plates include the Pacific Plate (PAC), North American Plate (NAS), Indian Plate (IND), and Australian Plate (AUS). Geologist Maria Silva led a team that calculated average melting points for these elements in the crust from different tectonic plates. Her team discovered that each of these elements exhibits slightly different melting points depending on whether it is found in the PAC, NAS, IDN, or AUS. For example, whereas the average melting point for aluminum from the North American Plate (NAS) is 663.5°C, the average point for ____

Which choice most effectively uses data from the table to complete the example?

aluminum from the Pacific Plate (PAC) is 660.3°C.
iron from the Australian Plate (AUS) is 1558°C.
silicon from the Indian Plate (IND) is 1420°C.
aluminum from the Indian Plate (IND) is 668.2°C
