Q157 (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 (Drug)</th><th style="border: 1px solid #888; padding: 8px;">List II (Effect)</th></tr></thead><tbody><tr><td style="border: 1px solid #888; padding: 8px;">(A) Nicotine</td><td style="border: 1px solid #888; padding: 8px;">(I) Causes sense of euphoria and increased energy</td></tr><tr><td style="border: 1px solid #888; padding: 8px;">(B) Morphine</td><td style="border: 1px solid #888; padding: 8px;">(II) Stimulates adrenal gland to release catecholamines into blood circulation</td></tr><tr><td style="border: 1px solid #888; padding: 8px;">(C) Heroin</td><td style="border: 1px solid #888; padding: 8px;">(III) Effective sedative and painkiller</td></tr><tr><td style="border: 1px solid #888; padding: 8px;">(D) Cocaine</td><td style="border: 1px solid #888; padding: 8px;">(IV) A depressant; slows down body function</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-II, B-III, C-I, D-IV
- A-III, B-II, C-I, D-IV
### Related Formula
$\begin{aligned}
\text{Nicotine} &\rightarrow \text{Stimulates adrenal medulla to release adrenaline/noradrenaline}\\
\text{Morphine} &\rightarrow \text{Potent sedative and painkiller}\\
\text{Heroin} &\rightarrow \text{Depressant that slows down body functions}\\
\text{Cocaine} &\rightarrow \text{Stimulants producing euphoria and increased energy}
\end{aligned}$
### Core Logic
Matching each drug to its specific physiological effect:
* (A) Nicotine $\rightarrow$ Stimulates adrenal gland to release catecholamines into blood circulation (II)
* (B) Morphine $\rightarrow$ Effective sedative and painkiller (III)
* (C) Heroin $\rightarrow$ A depressant; slows down body function (IV)
* (D) Cocaine $\rightarrow$ Causes sense of euphoria and increased energy (I)
### Step 1: Result
The correct combination is A-II, B-III, C-IV, D-I.
### Pattern Recognition
Sees: "Nicotine Morphine Heroin Cocaine".
Shortcut: Morphine = Painkiller (B-III), Cocaine = Euphoria (D-I).
