Solution
The correct option is B Mesonephric
On the basis of development, kidneys are of 3 types.
(1) Pronephric kidney: Develop from anterior part (pronephros) of nephrotome plate. Its nephrons are simple tubular in shape. Nephrons are not differentiated. For example, cyclostomes and tadpole of the frog.
(2) Mesonephric kidney: Develop from middle part (mesonephros) of nephrotome plate and remaining part of nephrotome is destroyed. Only Bowman's capsule is found in nephrons while remaining part is simple tubular. For example, most of the fishes and adult Amphibians.
(3) Metanephric Kidney: Develops from posterior part (metanephros) of nephrotome while remaining part is destroyed. Nephrons are well differentiated into Bowman's capsule, PCT, DCT and loop of Henle's eg. Reptile, Aves, Mammals.Therefore, the correct answer is option B.
