Question

Match the pair.

Column I (Hormone)	Column II (Function)
i.	Erythropoietin	a.	absorption of dietary calcium
ii.	Calcitriol	b.	water retention during severe dehydration
iii.	Renin	c.	production of RBC
iv.	Antidiuretic hormone	d.	increases blood pressure

Choose the correct option:

• A. \(\mathrm{i}-\mathrm{c},\mathrm{ii}-\mathrm{a},\mathrm{iii}-\mathrm{b},\mathrm{iv}-\mathrm{d}\).
• B. i - c, ii - b, iii - d, iv -a.
• C. \(\mathrm{i}-\mathrm{c},\mathrm{ii}-\mathrm{a},\mathrm{iii}-\mathrm{d},\mathrm{iv}-\mathrm{b}\).
• D. i - c, ii - d, iii - a, iv - b.

Hint:

Recall one function of each hormone: RBC production, calcium absorption, blood pressure and water retention.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept
Each hormone controls a particular physiological function.

Step 2: Match
Erythropoietin stimulates production of RBC, so i - c.
Calcitriol increases absorption of dietary calcium, so ii - a.
Renin raises blood pressure through the renin-angiotensin system, so iii - d.
ADH causes water retention during dehydration, so iv - b.

Step 3: Conclusion
The matching is i - c, ii - a, iii - d, iv - b.

Final Answer:
The correct pairing is i-c, ii-a, iii-d, iv-b. \[ \boxed{\text{(C) }\text{i - c, ii - a, iii - d, iv - b}} \]
