C. Chlorophyceae - chl a and chl b, Rhodophyceae - chl a, chl d and phycoerythrin and Phaeophyceae - chl a, chl c and fucoxanthin
D. Chlorophyceae - chl a and chl b, Phaeophyceae – chl a, chl d and fucoxanthin, and Rhodophyceae – chl a, chl c and phycoerythrin

Answer

To solve the question regarding algae and their respective chlorophylls, we need to analyze the different classes of algae and identify the chlorophylls associated with each class. Here’s a step-by-step breakdown:

### Step 1: Identify the Classes of Algae
There are three main classes of algae mentioned:
1. Chlorophyceae (Green algae)
2. Rhodophyceae (Red algae)
3. Phaeophyceae (Brown algae)

### Step 2: Determine the Chlorophylls in Each Class
- **Chlorophyceae**:
- Contains Chlorophyll A and Chlorophyll B.
- These chlorophylls are essential for photosynthesis.

- **Rhodophyceae**:
- Contains Chlorophyll A and Chlorophyll D.
- Additionally, it has a red pigment called phycoerythrin, which gives red algae their color.

- **Phaeophyceae**:
- Contains Chlorophyll A and Chlorophyll C.
- It also has a pigment called phycophycocyanin, which contributes to its color.

### Step 3: Match the Information with the Options
Now, we need to match the chlorophylls with the respective classes of algae:
- **Chlorophyceae**: Chlorophyll A and B
- **Rhodophyceae**: Chlorophyll A and D
- **Phaeophyceae**: Chlorophyll A and C

### Step 4: Identify the Correct Option
From the information above, we can conclude that the correct option will mention:
- Chlorophyceae having Chlorophyll A and B
- Rhodophyceae having Chlorophyll A and D
- Phaeophyceae having Chlorophyll A and C

### Conclusion
The correct option regarding algae and their respective chlorophylls is the one that accurately reflects the chlorophylls associated with each class.
