Which of the following statements about absorption spectrum is correct ?

Options

A. In blue region peak of Chl-b forms at lower wavelength than peak of Chl- 1
B. In red region height of peak of Chl-a is more than that of Chl-b
C. In blue region of peak of Chl-a is more than that of Chl-b
D. In red region peak of Chl-a forms at lower wavelength than that Chl-b

Answer

**Step-by-Step Solution:**

1. **Understanding Absorption Spectrum**: The absorption spectrum is a graph that shows the wavelengths of light absorbed by pigments, such as chlorophyll A, chlorophyll B, and beta-carotene. It indicates which colors of light are absorbed by these pigments during photosynthesis.

2. **Analyzing the Statements**: We need to evaluate the given statements about the absorption spectrum to determine which one is correct.

3. **Statement 1**: "In the blue region, chlorophyll B forms lower wavelength than peak of chlorophyll A."
- **Evaluation**: In the blue region, chlorophyll B absorbs light at a higher wavelength compared to chlorophyll A. Therefore, this statement is incorrect.

4. **Statement 2**: "In the red region, high peak of chlorophyll A than B."
- **Evaluation**: In the red region, the absorption peak of chlorophyll A is indeed higher than that of chlorophyll B. This statement is correct.

5. **Statement 3**: "In the blue region, the peak of chlorophyll A is more than B."
- **Evaluation**: In the blue region, chlorophyll B has a higher absorption peak than chlorophyll A. Thus, this statement is incorrect.

6. **Statement 4**: "In the red region, chlorophyll A forms lower than B."
- **Evaluation**: This statement is incorrect because chlorophyll A has a higher absorption peak than chlorophyll B in the red region.

7. **Conclusion**: The only correct statement is the second one: "In the red region, high peak of chlorophyll A than B."

**Final Answer**: The correct statement about the absorption spectrum is: "In the red region, high peak of chlorophyll A than B."
