Best answer
The correct choice is (d) Urea

The best explanation: Kidney stones or renal calculi is due to the formation of calcium oxalate which results in 60% of the kidney stones, calcium carbonate which results in 30% of the kidney stones and uric acid which results in 10-20% of the kidney stones.
