`{:("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 will analyze each item in Column I and find its corresponding match in Column II.

### Step-by-Step Solution:

1. **Identify Alitame (p)**:
- Alitame is known as an artificial sweetener. It is used to enhance the sweetness of food products.
- **Match**: (p) Alitame → (ii) Artificial sweetener

2. **Identify Iodoform (q)**:
- Iodoform is used as an antiseptic, particularly for treating wounds and infections.
- **Match**: (q) Iodoform → (iv) Antiseptic

3. **Identify Prontosil (r)**:
- Prontosil is recognized as the first synthetic antibacterial agent used to treat bacterial infections.
- **Match**: (r) Prontosil → (iii) Antibacterial agent

4. **Identify Terfenadine (s)**:
- Terfenadine is classified as an antihistamine, which is used to relieve allergy symptoms by blocking histamine receptors.
- **Match**: (s) Terfenadine → (i) Antihistamine

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

### Conclusion:
The correct matches are:
- P → II
- Q → IV
- R → III
- S → I

Thus, the appropriate choice from the options provided is **Option 2**.
