D. Monazite	4. Iron

• A. A-3, B-4, C-1, D-2
• B. A-4, B-2, C-1, D-3
• C. A-3, B-1, C-4, D-2
• D. A-2, B-4, C-3, D-1

Answer 1

The correct option is A A-3, B-4, C-1, D-2

Bauxite is the most important ore of aluminum which contains only 30–54% alumina, Al2O3; the rest is a mixture of silica, various iron oxides, and titanium dioxide along with trace amounts of zinc, phosphorous, nickel, vanadium etc

Hematite, also spelled as haematite, is a common iron oxide with a formula called Fe2O3 and has been widespread in rocks and soils

Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS)

The mineral monazite is a reddish-brown phosphate containing rare earth metals and an important source of thorium, lanthanum, and cerium
