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

Options

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

Answer

To solve the problem of matching Column I with Column II regarding the nomenclature of the restriction enzyme EcoRI, we need to analyze each component of the enzyme's name and its corresponding description.

### Step-by-Step Solution:

1. **Identify the components of EcoRI**:
- The name "EcoRI" can be broken down into four parts:
- **E**: Represents the first letter of the genus name.
- **co**: Represents the first two letters of the species name.
- **R**: Represents the name of the strain.
- **I**: Indicates that it is the first enzyme identified from that strain.

2. **Match each part with the descriptions**:
- **A. E**: This corresponds to the "Name of genus" (ii), as 'E' stands for Escherichia.
- **B. co**: This corresponds to the "Name of species" (iii), as 'co' stands for coli.
- **C. R**: This corresponds to the "Name of strain" (iv), as 'R' indicates the strain type.
- **D. I**: This corresponds to "1st in order of identification" (i), as 'I' signifies that it is the first enzyme identified.

3. **Compile the matches**:
- A (E) - (ii) Name of genus
- B (co) - (iii) Name of species
- C (R) - (iv) Name of strain
- D (I) - (i) 1st in order of identification

4. **Select the correct option**:
- Based on the matches:
- A-(ii), B-(iii), C-(iv), D-(i) corresponds to option (d).

### Final Answer:
The correct answer is (d) `A-(ii), B-(iii), C-(iv), D-(i)`.
