| (i) Renin - Enzyme that catalyses the formation of angiotensin I. |
| (ii) Aldosterone ? Regulates water reabsorption at the distal convoluted tubule. |
| (iii) Anti-diuretic hormone (ADH) - It is a powerful vasoconstrictor that stimulates the secretion of aldosterone. |

A) Only (i)
B) Only (iii)
C) (i), (ii) and (iii)
D) (ii), (iii) and (iv)
Correct Answer: A
Solution :
[a] Renin is an enzyme that catalyses the formation of angiotensin I. Aldosterone promotes reabsorption of sodium at distal convoluted tubule. Anti- diuretic hormone (ADH) regulates water reabsorption at the distal convoluted tubule. Angiotensin II is a powerful vasoconstrictor that stimulates the secretion of aldosterone.
