Match the column I with column II and mark the appropriate choice.
`{:("Column I","Column II"),("(p) Alitame","(i) Antihistamine"),("(q)lodoform","(ii) Artificial sweetener"),("(r) Prontosil","(iii) Antibacterial agent"),("(s) Terfenadine ","(iv) Antiseptic"):}`

Options

A. `(p)-(i), (q) - (ii) , (r) - (iv) , (s) - (iii)`
B. `(p)-(ii), (q) - (iv) , (r) - (iii) , (s) - (i)`
C. `(p)-(ii), (q) - (i) , (r) - (ii) , (s) - (iv)`
D. `(p)-(iv), (q) - (iii) , (r) - (i) , (s) - (ii)`

Answer

To solve the matching question, we need to identify the correct pairs from Column I and Column II based on the properties and uses of the compounds listed.

### Step-by-Step Solution:

1. **Identify Alitame (p)**:
- Alitame is known to be an artificial sweetener. It is significantly sweeter than sucrose and is used as a sugar substitute.
- **Match**: (p) Alitame → (ii) Artificial sweetener.

2. **Identify Iodoform (q)**:
- Iodoform (CHI3) is known for its antiseptic properties. It releases iodine slowly, which is effective in killing bacteria.
- **Match**: (q) Iodoform → (iv) Antiseptic.

3. **Identify Prontosil (r)**:
- Prontosil is a sulfonamide antibiotic that is used as an antibacterial agent. It was one of the first antibiotics discovered and is effective against bacterial infections.
- **Match**: (r) Prontosil → (iii) Antibacterial agent.

4. **Identify Terfenadine (s)**:
- Terfenadine is an antihistamine that is used to relieve allergy symptoms such as sneezing and runny nose. It blocks the action of histamine in the body.
- **Match**: (s) Terfenadine → (i) Antihistamine.

### Final Matching:
- (p) Alitame → (ii) Artificial sweetener
- (q) Iodoform → (iv) Antiseptic
- (r) Prontosil → (iii) Antibacterial agent
- (s) Terfenadine → (i) Antihistamine

### Conclusion:
The correct matching sequence is:
- P → ii
- Q → iv
- R → iii
- S → i

Thus, the answer is option 2: P2, Q4, R3, S1.
