Match the words present in Column-I with those present in Column-II.
`{:(,"Column-I",,"Column-II"),((A),"Widal test",(i),"Ringworms"),((B),"Haemophilus influenzae",(ii),"Ascariasis"),((C),"Rhino Viruses",(iii),"Common cold"),((D),"Trichophyton",(iv),"Pneumonia"),(,,(v),"Typhoid"),(,,(vi),"AIDS"):}`

Options

A. `{:("(A)",(B),(C),(D)),("(vi)",(iv),(iii),(i)):}`
B. `{:("(A)",(B),(C),(D)),("(v)",(iv),(iii),(i)):}`
C. `{:("(A)",(B),(C),(D)),("(v)",(iii),(iv),(ii)):}`
D. `{:("(A)",(B),(C),(D)),("(vi)",(iii),(iv),(ii)):}`

Answer

To solve the matching question, we need to correlate the items from Column-I with their respective items in Column-II based on their definitions or associations. Let's go through each item step by step:

### Step-by-Step Solution:

1. **Widal Test (A)**:
- The Widal test is a serological test used to diagnose typhoid fever.
- **Match**: A → (v) Typhoid

2. **Haemophilus influenzae (B)**:
- Haemophilus influenzae is a bacterium that can cause pneumonia.
- **Match**: B → (iv) Pneumonia

3. **Rhino Viruses (C)**:
- Rhino viruses are known to cause the common cold.
- **Match**: C → (iii) Common cold

4. **Trichophyton (D)**:
- Trichophyton is a genus of fungi that causes ringworm infections.
- **Match**: D → (i) Ringworms

### Final Matches:
- A → (v) Typhoid
- B → (iv) Pneumonia
- C → (iii) Common cold
- D → (i) Ringworms

### Summary of Matches:
- A (Widal test) → v (Typhoid)
- B (Haemophilus influenzae) → iv (Pneumonia)
- C (Rhino Viruses) → iii (Common cold)
- D (Trichophyton) → i (Ringworms)
