Question

\begin{table}[h] \centering \begin{tabular}{|c|l|c|l|} \hline \multicolumn{2}{|c|}{List I} & \multicolumn{2}{c|}{List II}
\hline A & Cortisol & I & Stimulates the formation of alveoli in mammary glands
B & Aldosterone & II & Produces anti-inflammatory reactions
C & Cholecystokinin & III & Stimulates reabsorption of $Na^+$ and water from renal tubule
D & Progesterone & IV & Stimulates secretion of pancreatic enzymes and bile juice
\hline \end{tabular} \end{table}Choose the correct answer from the options given below :}

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

Hint:

Logic Tip: Use functional keywords: Cortisol = Stress/Anti-inflammatory; Aldosterone = Sodium/Salt; CCK = Digestion/Bile; Progesterone = Pregnancy/Mammary.

Answer 1

The Correct Option is D

Concept:
The human endocrine system secretes various hormones that regulate distinct physiological processes. Matching these hormones to their specific target organs and primary actions is essential to understand metabolic and reproductive control.
Step 1:
Cortisol is the primary glucocorticoid secreted by the adrenal cortex. It plays a major role in carbohydrate metabolism, suppresses the immune response, and uniquely produces anti-inflammatory reactions. Match: A $\rightarrow$ II
Step 2:
Aldosterone is the main mineralocorticoid from the adrenal cortex. It acts primarily on the renal tubules (DCT and collecting duct) and stimulates the reabsorption of $Na^+$ and water, aiding in blood pressure regulation. Match: B $\rightarrow$ III
Step 3:
Cholecystokinin (CCK) is a gastrointestinal hormone secreted by the duodenum. It acts on both the pancreas and the gall bladder, stimulating the secretion of pancreatic enzymes and bile juice, respectively, to aid in digestion. Match: C $\rightarrow$ IV
Step 4:
Progesterone is a steroid hormone produced by the corpus luteum in the ovaries. During pregnancy, it supports fetal development and acts on the mammary glands to stimulate the formation of alveoli (sac-like structures that store milk). Match: D $\rightarrow$ I
Step 5:
Combining the verified matches yields the sequence A-II, B-III, C-IV, D-I. This corresponds exactly to Option (4).
