Step 1: Match Each Drug with Its Correct Use
Let’s examine each drug one by one and identify its correct pharmacological category:
- Veronal is a barbiturate derivative and is primarily used as a tranquilizer or sedative, not an antihistamine. So it should be matched with IV (Tranquillizer).
- Morphine is a well-known opioid used for relieving severe pain, so it is an analgesic, which matches with III.
- Seldane (Terfenadine) is used to treat allergic reactions, making it an antihistamine, matching with I.
Step 2: Final Matching
- A-IV: Veronal → Tranquillizer
- B-III: Morphine → Analgesic
- C-I: Seldane → Antihistamine
Final Answer:
Hence, the correct matching is A-IV, B-III, C-I, which corresponds to option (3).
