Correct option is C
The absorption spectra graph shows three peaks labeled A, B, and C. Option 3 states: A - chlorophyll b, B - chlorophyll a, C - carotenoid. Let's match this with the known absorption characteristics:
- Chlorophyll b has major absorption peaks around 453 nm and 642 nm.
- Chlorophyll a has major absorption peaks around 430 nm and 662 nm.
- Carotenoids have a broad absorption peak in the 400-500 nm range, often around 450-480 nm.
Upon closer inspection of the graph:
1.Peak A appears to have a significant absorption around 450-460 nm and a secondary peak around 640 nm, which aligns with the absorption spectrum of chlorophyll b.
2. Peak B shows a strong absorption around 430-440 nm and a prominent peak around 660-670 nm, matching the absorption spectrum of chlorophyll a.
3. Peak C exhibits a broad absorption in the 400-500 nm range, consistent with carotenoids.
Conclusion:
The reassignment of peaks based on the graph's features supports option 3: A - chlorophyll b, B - chlorophyll a, C - carotenoid.
