Question

Match the LIST-I with LIST-II: 
\[ \begin{array}{|l|l|} \hline \textbf{LIST I} & \textbf{LIST II} \\ \hline A. \ \text{Parathyroid} & I. \ \text{Gonadotropin} \\ B. \ \text{Pancreas} & II. \ \text{Parathormone} \\ C. \ \text{Pineal Gland} & III. \ \text{Insulin} \\ D. \ \text{Placenta} & IV. \ \text{Melatonin} \\ \hline \end{array} \]
Choose the correct answer from the options given below: 
 

• A. A - I, B - III, C - I, D - II
• B. A - I, B - III, C - II, D - IV
• C. A - II, B - III, C - IV, D - I
• D. A - IV, B - II, C - I, D - III

Hint:

Always connect glands with their signature hormones: Parathyroid → PTH, Pancreas → Insulin, Pineal → Melatonin, Placenta → hCG.

Answer 1

The Correct Option is C

Step 1: Recall hormone sources.
- Parathyroid gland secretes Parathormone (PTH), regulating calcium levels.
- Pancreas secretes Insulin, which regulates blood glucose levels.
- Pineal gland secretes Melatonin, controlling sleep-wake cycles.
- Placenta secretes Gonadotropins such as hCG, maintaining pregnancy.
Step 2: Match correctly.
A → II (Parathormone)
B → III (Insulin)
C → IV (Melatonin)
D → I (Gonadotropin)
Step 3: Analyze given options.
- (A) A - I, B - III, C - I, D - II: Incorrect, mismatched.
- (B) A - I, B - III, C - II, D - IV: Wrong, parathyroid does not secrete gonadotropin.
- (C) A - II, B - III, C - IV, D - I: Correct matches.
- (D) A - IV, B - II, C - I, D - III: Wrong combination.
Step 4: Conclusion.
Hence, the correct match is A - II, B - III, C - IV, D - I.
