The 30-Second Exam Hall Shortcut: ⚡ Swapped Classes: Both Statements are False!

⏱️ Save ~20 seconds

Aspirin and paracetamol are non-addictive over-the-counter painkillers $\implies$ NON-NARCOTIC analgesics! Morphine and heroin are addictive opium alkaloids that induce sleep and stupor $\implies$ NARCOTIC analgesics! The question has inverted both definitions: Statement I is false and Statement II is false! Match Option (2)!

1 Check Statement I: Aspirin and Paracetamol are non-narcotic analgesics (not narcotic) -> Statement I is FALSE.

2 Check Statement II: Morphine and Heroin are narcotic analgesics (not non-narcotic) -> Statement II is FALSE.

3 Both statements are false.

4 Match Option (2).

Step-by-Step Rigorous Workflow & Mathematical Proof

Step 1

NCERT Classification of Analgesics

Analgesics are neurological active drugs that relieve pain without causing impairment of consciousness, mental confusion, incoordination, or paralysis. NCERT categorizes analgesics into two distinct classes: 1. Non-narcotic (non-addictive) analgesics 2. Narcotic analgesics

Step 2

Evaluating Statement I: Aspirin and Paracetamol

Aspirin (acetylsalicylic acid) and paracetamol (4-acetamidophenol) are non-addictive antipyretics and analgesics that inhibit prostaglandin synthesis. They belong to the class of non-narcotic analgesics. Statement I asserts they are "narcotic analgesics", which is completely false.

Step 3

Evaluating Statement II: Morphine and Heroin

Morphine and its diacetyl derivative (heroin), along with codeine, are opiates that relieve severe pain and produce sleep/stupor. In poisonous doses, they produce stupor, coma, convulsions, and ultimate death, and are highly habit-forming. They are narcotic analgesics. Statement II asserts they are "non-narcotic analgesics", which is completely false.

Step 4

Conclusion

Both Statement I and Statement II are false, corresponding uniquely to Option (2).

4-Option Deep Scan

1 1

✗ Incorrect

Verdict & Scientific Reason:

Both definitions have been cross-swapped.

⚠️

Student Fallacy (Why candidates pick this trap): Assuming both statements are textbook facts without reading the swapped categories.

2 2

✓ 100% Correct

Verdict & Scientific Reason:

Both statements are factually false because their classes have been directly inverted.

💡

Why this is airtight: None; rigorous pharmaceutical pharmacology knowledge.

3 3

✗ Incorrect

Verdict & Scientific Reason:

Statement I is false (aspirin is non-narcotic).

⚠️

Student Fallacy (Why candidates pick this trap): Misclassifying aspirin as a narcotic.

4 4

✗ Incorrect

Verdict & Scientific Reason:

Statement II is false (morphine is narcotic).

⚠️

Student Fallacy (Why candidates pick this trap): Misclassifying morphine as non-narcotic.

⚠️

NTA Trap Alert: Inverted Category Matching Trap

Examiners frequently invert parallel definitions (swapping narcotic and non-narcotic). Students who read quickly may recognize all four drug names from the chapter and mark "Both are true" (Option 1).

🛡️ How to avoid the -1 mark: Cross-check each word: Aspirin = Non-narcotic. Morphine = Narcotic. Both statements swapped

\implies

Both are false.
