A Correct answer
Explanation

Calcium oxalate is the most common component of kidney stones, forming when there's excess calcium and oxalate in urine. The other options are not major kidney stone components. Sodium acetate and magnesium sulphate are salts, but pure calcium alone doesn't typically form stones.
