Question

Match List I with List II \begin{table}[h] \centering \begin{tabular}{|c|l|c|l|} \hline \multicolumn{2}{|c|}{List I (Drug)} & \multicolumn{2}{c|}{List II (Effect)}
\hline A & Nicotine & I & Causes sense of euphoria and increased energy
B & Morphine & II & Stimulates adrenal gland to release catecholamines into blood circulation
C & Heroin & III & Effective sedative and painkiller
D & Cocaine & IV & A depressant, slows down body function
\hline \end{tabular} \end{table} Choose the correct answer from the options given below:

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

Hint:

Logic Tip: Differentiate between the opiates! While Morphine is actively used in medicine as a "painkiller" (III), its derivative Heroin is highly abused and generally known as a severe "depressant" (IV) that slows body functions.

Answer 1

The Correct Option is A

Step 1 : Understanding the Question:
The question asks us to match different drugs or chemical substances with their physiological or psychological effects on the human body. This involves pharmacology and human health knowledge.
Step 2 : Key Formulas and Approach:
Categorize each drug based on its source and action:
1. Nicotine: Alkaloid/Stimulant of the endocrine system.
2. Opiates: Analgesics and depressants.
3. Cocaine: Alkaloid/CNS Stimulant.
Step 3 : Detailed Explanation:

Nicotine (A): Found in tobacco, nicotine is an alkaloid that stimulates the adrenal glands to release adrenaline and noradrenaline (catecholamines) into the blood. This increases heart rate and blood pressure. Thus, A matches with II.

Morphine (B): Extracted from the latex of the poppy plant, morphine is an opioid that acts on the central nervous system. It is used clinically as an effective sedative and painkiller, especially for patients undergoing surgery. Thus, B matches with III.

Heroin (C): Chemically known as diacetylmorphine, it is a semi-synthetic opioid. It acts as a depressant and generally slows down body functions. Thus, C matches with IV.

Cocaine (D): Derived from the coca plant, it interferes with the transport of dopamine. It has a potent stimulating action on the CNS, which causes a sense of euphoria and increased energy. Thus, D matches with I.

Step 4 : Final Answer:
Matching these according to their known biological effects gives the sequence A-II, B-III, C-IV, and D-I. This corresponds to the arrangement in option (A).
