D Correct answer
Explanation

Human kidneys develop through three embryological stages: pronephros (transient, non-functional), mesonephros (functional in embryo), and metanephros (permanent, functional adult kidney). Adult humans have metanephric kidneys, which are the most developed and efficient type. Opisthonephros is found in some lower vertebrates like fish and amphibians.
