Q169 (2024)
Match List I with List II:
<div style="overflow-x: auto; margin: 1rem 0;"><table style="width: 100%; border-collapse: collapse; text-align: left; font-size: 14px;"><thead><tr><th style="border: 1px solid #888; padding: 8px;">List-I</th><th style="border: 1px solid #888; padding: 8px;">List-II</th></tr></thead><tbody><tr><td style="border: 1px solid #888; padding: 8px;">(A) Cortisol</td><td style="border: 1px solid #888; padding: 8px;">(I) Stimulates the formation of alveoli in mammary glands</td></tr><tr><td style="border: 1px solid #888; padding: 8px;">(B) Aldosterone</td><td style="border: 1px solid #888; padding: 8px;">(II) Produces anti-inflammatory reactions</td></tr><tr><td style="border: 1px solid #888; padding: 8px;">(C) Cholecystokinin</td><td style="border: 1px solid #888; padding: 8px;">(III) Stimulates reabsorption of $Na^+$ and water from renal tubule</td></tr><tr><td style="border: 1px solid #888; padding: 8px;">(D) Progesterone</td><td style="border: 1px solid #888; padding: 8px;">(IV) Stimulates secretion of pancreatic enzymes and bile juice</td></tr></tbody></table></div>
Choose the correct answer from the options given below:
- A-III, B-II, C-IV, D-I
- A-II, B-III, C-IV, D-I
- A-IV, B-II, C-I, D-III
- A-II, B-III, C-I, D-IV
### Related Formula
$\begin{aligned}
\text{Cortisol} &\rightarrow \text{Anti-inflammatory and immunosuppressive response}\\
\text{Aldosterone} &\rightarrow \text{Reabsorption of } Na^+ \text{ and } H_2O \text{ at DCT}\\
\text{Cholecystokinin (CCK)} &\rightarrow \text{Pancreatic enzymes and gallbladder contraction (bile)}\\
\text{Progesterone} &\rightarrow \text{Mammary alveoli development}
\end{aligned}$
### Core Logic
Matching each hormone with its physiological function:
* (A) Cortisol $\rightarrow$ Produces anti-inflammatory reactions (II)
* (B) Aldosterone $\rightarrow$ Stimulates reabsorption of $Na^+$ and water from renal tubule (III)
* (C) Cholecystokinin $\rightarrow$ Stimulates secretion of pancreatic enzymes and bile juice (IV)
* (D) Progesterone $\rightarrow$ Stimulates the formation of alveoli in mammary glands (I)
### Step 1: Result
The correct combination is A-II, B-III, C-IV, D-I.
### Pattern Recognition
Sees: "Cortisol Aldosterone Cholecystokinin Progesterone".
Shortcut: Cortisol = Anti-inflammatory (A-II); Progesterone = Mammary alveoli (D-I).
