The correct option is A Renal calculus
Kidney stones, or renal calculi, are solid masses made of crystallized salts of oxalate. Kidney stones usually originate in your kidneys but can develop anywhere along your urinary tract. The urinary tract includes the kidneys, ureters, bladder, and urethra. Depending on this and the composition of the stone, they have different names. This is an extremely painful condition that causes a blockage of the urine passage from the kidneys to the ureters.
