Answer

To solve the question of matching the genes of the Lac operon with their respective products, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Genes and Their Functions:**
- The Lac operon consists of several genes: i gene, z gene, a gene, and y gene.
- Each of these genes produces specific proteins that play a role in the metabolism of lactose.

2. **Match Each Gene with Its Product:**
- **i gene:** This gene produces the repressor protein that inhibits the transcription of the operon when lactose is not present.
- **Match:** i gene → (iii) Repressor
- **z gene:** This gene encodes for beta-galactosidase, an enzyme that breaks down lactose into glucose and galactose.
- **Match:** z gene → (i) Beta-galactosidase
- **a gene:** This gene produces transacetylase, which is involved in the metabolism of lactose.
- **Match:** a gene → (iv) Transacetylase
- **y gene:** This gene encodes for permease, which facilitates the transport of lactose into the cell.
- **Match:** y gene → (ii) Permease

3. **Compile the Matches:**
- Now we can compile the matches:
- (a) i gene → (iii) Repressor
- (b) z gene → (i) Beta-galactosidase
- (c) a gene → (iv) Transacetylase
- (d) y gene → (ii) Permease

4. **Select the Correct Option:**
- Based on the matches, we can conclude that the correct option is:
- A → iii
- B → i
- C → iv
- D → ii

### Final Answer:
The correct matches are:
- (a) i gene → (iii) Repressor
- (b) z gene → (i) Beta-galactosidase
- (c) a gene → (iv) Transacetylase
- (d) y gene → (ii) Permease

Thus, the correct option is **4**.
