Explanation

The correct answer is calcium oxalate. Most kidney stones, approximately 75 to 80 percent, are composed of calcium oxalate crystals. These stones form when urine becomes oversaturated with calcium and oxalate, leading to the formation of solid crystals in the kidneys. While uric acid and other compounds can also form stones, calcium oxalate is by far the most common chemical compound identified in medical cases.
