Options

A. It is a biological processes occurring in plants, algae and some bacteria.
B. carbon dioxide from the atmosphere is used for making carbohydrates, and starch
C. Light energy is initially absorbed by various chlorophyll molecules and accessory pigments
D. All are correct

Answer

To solve the question "Select a correct statement for photosynthesis," we will analyze the provided statements one by one to determine which one is correct.

### Step-by-Step Solution:

1. **Identify the statements**: We have multiple statements regarding photosynthesis that need to be evaluated for correctness.

2. **Evaluate the first statement**:
- The statement claims that photosynthesis is a biological process occurring in plants, algae, and some bacteria.
- **Analysis**: This is correct. Photosynthesis does occur in these organisms, specifically in plants and algae (which contain chlorophyll) and certain bacteria like cyanobacteria.

3. **Evaluate the second statement**:
- This statement says that carbon dioxide from the atmosphere is used for making carbohydrates and starch.
- **Analysis**: This is also correct. During photosynthesis, carbon dioxide is fixed during the Calvin cycle to produce glucose, which can then be stored as starch.

4. **Evaluate the third statement**:
- The statement mentions that light energy is initially absorbed by various chlorophyll molecules and accessory pigments.
- **Analysis**: This statement is correct as well. Chlorophyll absorbs light energy, and accessory pigments help absorb additional wavelengths of light that chlorophyll cannot, thus enhancing the photosynthesis process.

5. **Evaluate the fourth statement**:
- This statement claims that all the previous statements are correct.
- **Analysis**: Since the first three statements are indeed correct, this statement is also correct.

6. **Conclusion**: All the statements provided are correct regarding photosynthesis.

### Final Answer:
The correct answer is that all statements regarding photosynthesis are correct.
