E. Renal corpuscle

Column II i. Formation of concentrated urine ii. Filtration of blood iii. Reabsorption of 70-80% of electrolytes iv. Ionic balance v. Maintenance of concentration gradient in medulla

A

A-iii, B-v, C-iv, D-ii, E-i

B

A-iii, B-iv, C-i, D-v, E-ii

C

A-i, B-iii, C-ii, D-v, E-iv

D

A-iii, B-v, C-iv, D-ii, E-i

Correct Answer

Option B

Detailed Explanation

Proximal convoluted tubule is responsible for reabsorption of 70-80% of electrolytes. Distal convoluted tubule maintains ionic balance. Henle's loop forms concentrated urine. Counter-current mechanism maintains the concentration gradient in the medulla. Renal corpuscle is involved in the filtration of blood.
