Correct Answer
(B) a-iv, b-i, c-ii, d-iii
Solution & Explanation
Answer: (B) a-iv, b-i, c-ii, d-iii. Solution: Ultrafiltration (a) occurs at the Malpighian corpuscle/renal corpuscle (iv) where blood is finely filtered through the glomerulus and Bowman's capsule. Concentration of urine (b) involves Henle's loop (i). Transport of urine (c) is by the ureter (ii), and storage of urine (d) is in the urinary bladder (iii). NCERT Reference: Ch 16, p.208, lines 41-46 — "The epithelial cells of Bowman’s capsule called podocytes... Therefore, it is considered as a process of ultra filtration."; p.212, lines 39-41 — "Urine formed by the nephrons is ultimately carried to the urinary bladder where it is stored".
