Which of the following are found in the surface waters of the sea?

Options

A. Red algae
B. Benthic forms
C. Green algae
D. Brown algae

Answer

To determine which organisms are found in the surface waters of the sea, we need to analyze the options provided: red algae, benthic forms, green algae, and brown algae.

### Step-by-Step Solution:

1. **Understanding the Options**:
- **Red Algae**: Typically found in deeper waters. They thrive in deeper marine environments and are not commonly found at the surface.
- **Benthic Forms**: These organisms live on the ocean floor and are not associated with surface waters.
- **Green Algae**: These are commonly found in surface waters. They can perform photosynthesis, which allows them to thrive in well-lit areas near the surface.
- **Brown Algae**: Generally found in the mid-intertidal zones and deeper waters, not predominantly in the surface layer.

2. **Analyzing the Habitat**:
- Surface waters are characterized by light availability, which is crucial for photosynthesis. Green algae are adapted to these conditions, making them prevalent in these areas.

3. **Conclusion**:
- Based on the analysis, the organism that is found in the surface waters of the sea is **Green Algae**.

### Final Answer:
The correct answer is **Green Algae**.
