Options

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

Answer

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

### Step-by-Step Solution:

1. **Identify Lactoferritin**:
- Lactoferritin is a hormone injected into cows to prevent mastitis (breast inflammation).
- **Match**: (A) Lactoferritin → (iii) Prevents mastitis in cows.

2. **Identify Polygalacturonase**:
- Polygalacturonase is an enzyme that dissolves the cell wall in tomatoes, leading to fruit softening and earlier rotting. It is used in the Flavr Savr tomato to increase shelf life by blocking this enzyme.
- **Match**: (B) Polygalacturonase → (iv) Flavr Savr.

3. **Identify Human Lactalbumin**:
- Human lactalbumin is found in the milk of transgenic cow Rosie, which produces human protein-enriched milk that is nutritionally balanced for human babies.
- **Match**: (C) Human lactalbumin → (ii) Rosie.

4. **Identify Spider-silk Protein**:
- Spider-silk protein is produced by transgenic goats that have had spider genes spliced into their cells, allowing them to produce silk along with milk. This silk has various applications, including medical sutures.
- **Match**: (D) Spider-silk protein → (i) Molecular farming in goat.

### Final Matches:
- (A) Lactoferritin → (iii) Prevents mastitis in cows
- (B) Polygalacturonase → (iv) Flavr Savr
- (C) Human lactalbumin → (ii) Rosie
- (D) Spider-silk protein → (i) Molecular farming in goat

### Answer:
- A → iii
- B → iv
- C → ii
- D → i
