Kidneys are the organs involved in the excretory system. The malformation of the two ureters and two renal pelvis is due to the premature division of the ureteric bud. Thus, option E is correct.
<h3>What is a kidney?</h3>
A kidney has been the organ that filters wastes and absorbs the nutrient from the body fluid. It is located in the abdominal cavity and is made of nephrons that are in turn made of glomerulus involved in the blood filtration.
The uretic bud has been known to arise from the nephric duct that promotes nephrogenesis. These are preprogrammed for the repetitive divisions that result in the duplication of the renal pelvis and the ureter of the excretory system.
This premature division of the uretic bud leads to the formation of two ureters and two pelves when the bud comes in contact with metanephric blastema. This event may result in two kidney formations.
Therefore, option E. the uretic bud undergoing a premature division leads to malformation.
