Match List I with List II and select the correct option :
`{:(" List I" , " List II"),(" i. Bacillus thuringiensis " , 1" Production of chitinase"),(" ii. Rhizobium meliloti" , 2." Scavenging of oil spills"),(" iii. Escherichia coli " , 3. " Incorporation of 'nif' gene"),(" iv Peudomonas putida " , 4. " Production of Bt toxin "),(" v. Trichoderma" , 5. " Production of human insulin"):}`

Options

A. i-2, ii-4, iii-1,iv-5, v-3
B. i-2,ii-4,iii-5,iv-1,v-3
C. i-4,ii-3,iii-5,iv-2,v-1
D. i-3,ii-4,iii-5,iv-1,v-2

Answer

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

### Step-by-Step Solution:

1. **Identify Bacillus thuringiensis**:
- Bacillus thuringiensis is known for producing a toxin called Bt toxin, which is used in pest control.
- **Match**: Bacillus thuringiensis → Production of Bt toxin (4).

2. **Identify Rhizobium meliloti**:
- Rhizobium meliloti is a nitrogen-fixing bacterium that incorporates the 'nif' gene, which is essential for nitrogen fixation.
- **Match**: Rhizobium meliloti → Incorporation of 'nif' gene (3).

3. **Identify Escherichia coli**:
- Escherichia coli (E. coli) is widely used in biotechnology for the production of human insulin through recombinant DNA technology.
- **Match**: Escherichia coli → Production of human insulin (5).

4. **Identify Pseudomonas putida**:
- Pseudomonas putida is known for its ability to degrade environmental pollutants, including its role in the bioremediation of oil spills.
- **Match**: Pseudomonas putida → Scavenging of oil spills (2).

5. **Identify Trichoderma**:
- Trichoderma is a genus of fungi that is known for producing chitinase, an enzyme that breaks down chitin.
- **Match**: Trichoderma → Production of chitinase (1).

### Final Matches:
- i. Bacillus thuringiensis → 4
- ii. Rhizobium meliloti → 3
- iii. Escherichia coli → 5
- iv. Pseudomonas putida → 2
- v. Trichoderma → 1

### Summary of Matches:
- **i → 4**
- **ii → 3**
- **iii → 5**
- **iv → 2**
- **v → 1**

### Correct Option:
The correct option that matches all the pairs is **Option 3**.
