Explanation
Kidney stones are produced due to the crystallization of certain substances in the urine. Out of the options provided, option C: Crystallisation of oxalates is the correct answer.
Oxalates are naturally occurring substances found in many foods, including fruits, vegetables, and nuts. When the concentration of oxalates in the urine becomes too high, they can crystallize and form kidney stones. Other substances that can form kidney stones include calcium, uric acid, and struvite.
Once these crystals form, they can grow in size and become lodged in the urinary tract, causing pain and discomfort. Treatment options for kidney stones include drinking plenty of water to help flush them out, medications to manage pain and discomfort, and in some cases, surgical intervention to remove the stones.
