Question

Match hormones given in Column I with their source gland in Column II.
\begin{tabular}{|l|c|l|c|} \hline \multicolumn{2}{|c|}{Column I} & \multicolumn{2}{c|}{Column II} \\ \hline i. & Oxytocin & a. & Adrenal medulla \\ ii. & Melatonin & b. & Thyroid gland \\ iii. & Catecholamines & c. & Pineal gland \\ iv. & Calcitonin & d. & Hypothalamus \\ \hline \end{tabular}
Choose the correct option from below.

• A. i - a ii - c iii - d iv - b
• B. i - d ii - a iii - b iv - c
• C. i - d ii - c iii - a iv - b
• D. i-c ii-d iii-a iv-b

Hint:

Hormone sources: Hypothalamus → Oxytocin, Pineal → Melatonin, Adrenal → Catecholamines, Thyroid → Calcitonin.

Answer 1

The Correct Option is C

Concept:
Hormones are secreted by specific endocrine glands and each has a characteristic source.

Step 1: Match each hormone with its source.
• Oxytocin → Synthesized in hypothalamus (released via posterior pituitary) → (d)
• Melatonin → Secreted by pineal gland → (c)
• Catecholamines (adrenaline, noradrenaline) → Adrenal medulla → (a)
• Calcitonin → Thyroid gland → (b)

Step 2: Verify combination. \[ i-d,\; ii-c,\; iii-a,\; iv-b \]

Step 3: Conclusion. \[ \text{Correct matching = Option (C)} \]
