Explanation:

1 is true everyone knows that . The mineral monazite is a reddish-brown phosphate containing rare earth metals and an important source of thorium, lanthanum, and cerium. Because of the presence of thorium within monazite, it can be radioactive.
3rd is also true, No risk of proliferation with thorium
2nd is also true as it is wrt per unit mass of mined mineral <4times more energy>

Hence option 4th is correct.
