Some species of fish can be cultured in a single fish pond. These fish do not compete for food as they have different food habits. In the following options fish are paired with their food habits. Select the incorrect match.

Options

A. Labeo rohita - Column feeder
B. Catla catla - Surface feeder
C. Cirrhinus mrigala - Bottom feeder
D. Common carp - Surface feeder

Explanation

To solve the question about identifying the incorrect match of fish species with their food habits, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: We need to identify which fish species is incorrectly paired with its food habit. The fish species are matched with their respective feeding habits.

2. **Identify the Fish Species and Their Feeding Habits**:
- **Labio rohita**: This fish is known as a column feeder. It primarily feeds in the middle layer of the water column.
- **Katla**: This species is identified as a surface feeder, feeding on phytoplankton found at the water's surface.
- **Phyrinus myrgula**: This fish is a bottom dweller, feeding on zooplankton from the bottom of the pond.
- **Common Carp**: This species is said to be a surface feeder, but it is actually a bottom feeder.

3. **Analyze Each Match**:
- For **Labio rohita**, the match is correct as it is a column feeder.
- For **Katla**, the match is also correct as it feeds on phytoplankton at the surface.
- For **Phyrinus myrgula**, the match is correct since it feeds on zooplankton at the bottom.
- For **Common Carp**, the match is incorrect because it is a bottom feeder, not a surface feeder.

4. **Conclusion**: The incorrect match is the **Common Carp**, which is incorrectly labeled as a surface feeder when it actually feeds from the bottom.

### Final Answer:
The incorrect match is **Common Carp - Surface feeder**.
