Pair 2 is correct: Bauxite is the principal ore from which aluminium is extracted through refining processes, mainly the Bayer process.
Pair 3 is not correct: While lithium plays a vital role in energy storage systems, particularly in lithium-ion batteries used for solar power systems, it is not involved in the direct manufacturing of solar panels. Solar panels are primarily made from silicon, with other materials like cadmium or tellurium used in some types of panels.
