Question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Thorium is a by-product of the extraction of rare earths from monazite sands. Reason (R): India's Kakrapara-1 reactor is the world's first reactor which uses thorium. In the light of the above statements, choose the correct answer from the options given below:

• A. Both A and R are true and R is the correct explanation of A.
• B. Both A and R are true but R is NOT the correct explanation of A.
• C. A is true but R is false.
• D. A is false but R is true.

Hint:

\[ \boxed{ \begin{aligned} \text{Monazite Sands} &\rightarrow \text{Rare Earths + Thorium}, \text{Kakrapar-1} &\rightarrow \text{PHWR (Uranium Fuel)}. \end{aligned} } \] Mnemonic: “Monazite gives Thorium; Kakrapar is not a Thorium reactor.”

Answer 1

The Correct Option is C
