The stones formed in human kidney consist mostly of
- Acalcium oxalateCorrect
- Bsodium acetate
- Cmagnesium sulphate
- Dcalcium
Explanation
The correct answer is A. Kidney stones, also known as renal calculi, are most commonly composed of calcium oxalate. This occurs when urine contains more calcium and oxalate than the fluid can dilute, leading to the formation of hard crystals. Calcium oxalate stones account for approximately 75 to 80 percent of all kidney stone cases. Calcium phosphate is another common component, but oxalate is the predominant substance found in these stones. Sodium acetate, magnesium sulphate, and pure calcium do not typically form the structural mass of human kidney stones.
