• B. 2 and 3 only
• C. 1 and 3 only
• D. All of the above

Answer 1

Answer:

A. 1 and 2 only

• Correct Answer: Option A) 1 and 2 only

• Monazite found in the coastal sands is a source of thorium - This statement is correct. Monazite is a reddish-brown phosphate mineral that contains rare earth elements and is one of the principal sources of thorium. In Kerala, monazite is found in beach sands along the coastal regions, particularly in areas like Chavara (Kollam district) and Aluva.

• Thorium is used in nuclear power production - This statement is correct. Thorium (Th-232) can be used as a nuclear fuel in nuclear reactors. India has significant thorium reserves and has developed a three-stage nuclear power program that aims to utilize thorium as a sustainable nuclear fuel.

• Kerala ranks second in India in monazite production - This statement is incorrect. Kerala actually ranks first in India in monazite production, not second. The coastal regions of Kerala, particularly in Kollam and Alappuzha districts, are rich in monazite deposits and contribute significantly to India's monazite reserves.
