The correct answer is D) thorium
Monazite is an important ore for a number of rare earth metals, including thorium, lanthanum, and cerium.
After extraction from monazite ore, thorium can be used in the generation of thorium-based nuclear power. Monazite is a reddish- or yellowish-brown mineral, a phosphate of cerium and lanthanum, and is the principal ore of thorium.
