Match column I with column II and select the correct option from the given codes
`{:(,"Column I",,"Column I"),("A.",alpha-1-"antitrypsin","(i)","AIDS"),("B.","Transposon","(ii)","Gene therapy"),("C.","ELISA","(iii)","Emphysema"),("D.","Retroviral vector","(iv)","Mobile genetic element"):}`

Options

A. A-(iii),B-(iv),C-(ii),D-(i)
B. A-(iii),B-(ii),C-(iv),D-(i)
C. A-(ii),B-(iv),C-(iii),D-(i)
D. A-(i),B-(iv),C-(ii),D-(iii)

Answer

To solve the matching question, we will analyze each item in Column I and find its corresponding match in Column II.

**Step 1: Analyze "A. alpha-1-antitrypsin"**
- Alpha-1-antitrypsin is a protein that protects the lungs and liver from damage. A deficiency in this protein can lead to emphysema, a lung condition.
- **Match:** (A) alpha-1-antitrypsin → (iii) Emphysema

**Step 2: Analyze "B. Transposon"**
- Transposons are mobile genetic elements that can move within the genome. They are often referred to as "jumping genes."
- **Match:** (B) Transposon → (iv) Mobile genetic element

**Step 3: Analyze "C. ELISA"**
- ELISA stands for Enzyme-Linked Immunosorbent Assay, which is a test used to detect the presence of antibodies, including those for HIV, which causes AIDS.
- **Match:** (C) ELISA → (i) AIDS

**Step 4: Analyze "D. Retroviral vector"**
- Retroviral vectors are used in gene therapy to deliver genetic material into cells. They are particularly used in the treatment of genetic disorders.
- **Match:** (D) Retroviral vector → (ii) Gene therapy

**Final Matches:**
- A → (iii) Emphysema
- B → (iv) Mobile genetic element
- C → (i) AIDS
- D → (ii) Gene therapy

**Correct Option:**
The correct option based on the matches is:
- A with iii
- B with iv
- C with i
- D with ii

Thus, the correct answer is option **A**.
