Among the following finely dissected leaves are found in

Options

A. free floating plants
B. submerged hydrophytes
C. emerged hydrophytes
D. all of the above

Answer

To solve the question regarding which type of plant has finely dissected leaves, we can analyze each option provided:

1. **Free Floating Plants**:
- These plants typically have leaves that are not finely dissected. Instead, they often have a distinct midrib and can appear cup-shaped. Therefore, this option does not fit the description of having finely dissected leaves.

2. **Submerged Hydrophytes**:
- Submerged hydrophytes are known for having finely dissected leaves. These leaves are usually dissected along the midrib, giving them a feather-like appearance. This characteristic aligns perfectly with the question about finely dissected leaves.

3. **Immersed Hydrophytes**:
- Immersed hydrophytes may have leaves that appear circular in shape. This does not correspond to the description of finely dissected leaves, so this option is also not correct.

4. **All of the Above**:
- Since only the submerged hydrophytes are known for having finely dissected leaves, this option cannot be correct.

Based on the analysis above, the correct answer to the question is **Submerged Hydrophytes**.

### Steps to arrive at the solution:
1. **Analyze each option**: Evaluate the characteristics of free floating plants, submerged hydrophytes, immersed hydrophytes, and the option of all of the above.
2. **Identify the key feature**: Focus on the specific feature mentioned in the question, which is "finely dissected leaves."
3. **Eliminate incorrect options**: Rule out options that do not match the description of having finely dissected leaves.
4. **Select the correct answer**: Conclude that submerged hydrophytes are the only type that fits the description.
