D. Viruses , fungi and bacteria .

Answer

**Step-by-Step Solution:**

1. **Understanding Carbohydrates**: Carbohydrates are organic compounds consisting of carbon, hydrogen, and oxygen, and they are the most abundant biomolecules on Earth.

2. **Identifying the Primary Form of Carbohydrates**: The primary form of carbohydrates produced is glucose (C6H12O6).

3. **Recognizing the Process of Production**: Carbohydrates, particularly glucose, are produced through the process of photosynthesis.

4. **Identifying the Organisms Involved**:
- Photosynthesis is primarily carried out by green plants.
- Algae also perform photosynthesis.
- Certain types of bacteria, known as photosynthetic bacteria, can also carry out this process.

5. **Understanding the Requirements for Photosynthesis**:
- Chlorophyll, a green pigment, is essential as it absorbs sunlight.
- Sunlight provides the energy needed for the conversion of carbon dioxide and water into glucose.
- Carbon dioxide from the atmosphere is fixed during this process.
- Water is also required, which undergoes photolysis (the splitting of water molecules).

6. **Byproducts of Photosynthesis**: Oxygen is released into the atmosphere as a byproduct of photosynthesis.

7. **Evaluating the Options**:
- The question provides options regarding which organisms produce carbohydrates.
- The correct option includes green plants, algae, and certain bacteria, as they all perform photosynthesis.

8. **Conclusion**: Therefore, the correct answer to the question is that carbohydrates are produced by green plants, algae, and some bacteria through the process of photosynthesis.

**Final Answer**: Carbohydrates are produced by green plants, algae, and some bacteria through the process of photosynthesis.
