Answer:

(c) Thorium ✅

Explanation:

Monazite sand is a rich source of thorium, a radioactive element used in nuclear energy production. It is primarily found along the coastal regions of India, especially in Kerala, Tamil Nadu, and Odisha.

Points:

• Thorium-rich mineral: Monazite contains thorium, uranium, and rare earth elements.
• Nuclear energy potential: Thorium can be used as a nuclear fuel.
• Found in India: Major reserves exist in the coastal sands of Kerala, Tamil Nadu, Andhra Pradesh, and Odisha.

Monazite sand is an important natural resource for India’s nuclear energy program, as thorium can serve as a sustainable fuel alternative in nuclear reactors. ⚛️⛏️
