The Correct Option is A
Solution and Explanation
Concept:
Thorium extraction involves conversion of ore into chloride form for metallurgical processing.
A common route:
\[
\text{Thorium oxalate} \rightarrow \text{ThCl}_4
\]
Step 1: Understand feed material.
Thorium is often precipitated as thorium oxalate: \[ Th(C_2O_4)_2 \]
Step 2: Conversion step.
Oxalate is converted to chloride using hydrochloric acid and heating: \[ \rightarrow ThCl_4 \] Final Answer: \[ \boxed{\text{Thorium oxalate}} \]
