Options
- AA - 2, B - 1, C - 3, D - 4
- BA - 1, B - 2, C - 4, D - 3
- CA - 4, B - 3, C - 1, D - 2
- DA - 3, B - 4, C - 2, D - 1
Correct answer
A. A - 2, B - 1, C - 3, D - 4
Step-by-step solution
A - 2: Photosystem I (PS I) has a reaction centre chlorophyll a with an absorption peak at 700 nm, known as P700. B - 1: Photosystem II (PS II) has a reaction centre chlorophyll a with an absorption peak at 680 nm, known as P680. C - 3: The Light Harvesting Complex (LHC) organizes pigments to absorb various wavelengths of light. D - 4: The reaction centre is where high-energy chemical intermediates, ATP and NADPH, are formed.
