`{:(,"Common name",,"Scientific name"),((i),"Bombay duck",,"Harpadon"),((ii),"Pomphret",,"Stromateus"),((iii),"Salmon",,"Anguilla"),((iv),"Sardine",,"Aluitheronema"),((v),"Singhi",,"Heteropneustes"),(,,,):}`

Options

A. (ii) and (v)
B. (i) and (iii)
C. (iii) and (v)
D. (iii) and (iv)

Explanation

To solve the question, we need to identify which of the common names and their corresponding scientific names are not correctly matched. We will analyze each option step by step.

### Step-by-Step Solution:

1. **Bombay Duck**:
- Common Name: Bombay Duck
- Scientific Name: Harpadon
- **Analysis**: This match is correct. Harpadon is indeed the scientific name for Bombay Duck.

2. **Pomphret**:
- Common Name: Pomphret
- Scientific Name: Stromateus
- **Analysis**: This match is also correct. Stromateus is the scientific name for Pomphret.

3. **Salmon**:
- Common Name: Salmon
- Scientific Name: Anguilla
- **Analysis**: This match is incorrect. The correct scientific name for Salmon is Salmo, not Anguilla (which is the scientific name for Eels).

4. **Sardine**:
- Common Name: Sardine
- Scientific Name: Aleutheronema
- **Analysis**: This match is incorrect. The scientific name for Sardine is Sardina, specifically Sardina pilchardus.

5. **Singhi**:
- Common Name: Singhi
- Scientific Name: Heteropneustes
- **Analysis**: This match is correct. Heteropneustes is indeed the scientific name for Singhi.

### Conclusion:
The incorrectly matched scientific names are for Salmon (which should be Salmo) and Sardine (which should be Sardina). However, since the question asks for which is not correctly matched, the third option (Salmon - Anguilla) is the primary incorrect match.

### Final Answer:
The option that is not correctly matched is:
**(iii) "Salmon", "Anguilla"**
