The correct answer is option-1 Bauxite. Bauxite is a sedimentary rock that is the primary ore of aluminum. It is typically found in tropical and subtropical regions, often near the Earth`s surface. Bauxite is formed through the weathering of aluminum-rich rocks over long periods of time.
In the given map, the solid rectangles represent the deposits of a specific mineral. These rectangles indicate the locations where bauxite deposits are found. By identifying the areas with solid rectangles, we can determine the presence of bauxite in those regions.
It`s important to note that the other options, copper, magnesium, and zinc, are not depicted by the solid rectangles on the map. Therefore, option-1, bauxite, is the correct answer.
