• B. 1-d-iii, 2-c-iv, 3-b-i, 4-a-ii
• C. 1-b-i, 4-a-iii, 3-c-ii, 2-d-iv
• D. 2-c-ii, 1-b-i, 4-c-iv, 3-c-iii
• E. 2-c-iv, 3-a-ii, 1-d-iii, 4-b-i

Answer 1

The correct option is B 1-d-iii, 2-c-iv, 3-b-i, 4-a-ii

1. Melatonin is secreted from pineal gland and regulates diurnal rhythm of body.

2. MSH (Melanocyte stimulating hormone) is secreted from intermediate lobe of pituitary gland and acts on melanocytes to secrete melanin which regulates pigmentation.

3. Aldosterone is secreted from adrenal gland and acts on renal tubules to stimulate water absorption.

4. TCT (Thyrocalcitonin) is secreted from thyroid gland and regulates blood calcium level.

So, the correct answer is '1-d-iii, 2-c-iv, 3-b-i, 4-a-ii'.
