(c)	Analgesics	(iii)	Cimetidine
(d)	Antimicrobials	(iv)	Seldane

• A. (a)-(iii), (b)-(ii), (c)-(iv), (d) - (i)
• B. (a)-(iii), (b)-(iv), (c)- (ii), (d)-(i)
• C. (a)-(i), (b)-(iv), (c)- (ii), (d)-(iii)
• D. (a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
This question involves matching medicinal chemicals with their respective therapeutic classifications.
Step 2: Detailed Explanation:
Matching the drugs based on their pharmaceutical actions:
- (a) Antacids: These are used to reduce acidity in the stomach. Cimetidine (Tegamet) was developed to prevent the interaction of histamine with receptors in the stomach wall, reducing acid secretion. $\rightarrow$ (iii)
- (b) Antihistamines: These are used to treat allergies by blocking histamine receptors. Seldane (Terfenadine) is a well-known antihistamine. $\rightarrow$ (iv)
- (c) Analgesics: These are pain relievers. Morphine is a powerful narcotic analgesic derived from the opium poppy. $\rightarrow$ (ii)
- (d) Antimicrobials: These are used to kill or inhibit the growth of microorganisms. Salvarsan (Arsphenamine) was the first effective treatment for syphilis, acting as an antimicrobial. $\rightarrow$ (i)
Step 3: Final Answer:
The correct matching is: (a)-(iii), (b)-(iv), (c)-(ii), (d)-(i). This corresponds to option (2).
