Which one of the following fishes is a surface feeder?

Options

A. Rohus
B. Mrigals
C. Common carps
D. Catlas

Explanation

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks which fish is a surface feeder. Surface feeders are fish that feed at the top of the water, often consuming insects and other food items that float on the surface.

2. **Identify the Options**: The options provided are Rohis, Mriguls, Common Carps, and Catlas. We need to analyze these options to determine which one is a surface feeder.

3. **Define Surface Feeders**: Surface feeder fishes typically have physical adaptations that allow them to feed at the water's surface. These adaptations include an upturned mouth that helps them scoop food from the surface.

4. **Analyze Each Option**:
- **Rohis**: Typically not known for surface feeding.
- **Mriguls**: Primarily feed in the water column and not specifically at the surface.
- **Common Carps**: They are bottom feeders and do not primarily feed at the surface.
- **Catlas**: Known to have an upturned mouth and are adapted to feed on insects and food at the water's surface.

5. **Conclusion**: Based on the analysis, the fish that is a surface feeder is the **Catlas**.

**Final Answer**: The correct answer is **Catlas**.
