Difference in the structure of different pigments:

Explanation

Option A is correct.Yes, the difference in the structure of different pigments can increase the range of light wavelengths being absorbed. This is because different pigments have different absorption spectra, meaning that they absorb different wavelengths of light. For example, chlorophyll a absorbs light in the blue-green and red regions of the spectrum, while chlorophyll b absorbs light in the blue-green, yellow, and red regions of the spectrum. This means that chlorophyll a and chlorophyll b can absorb a wider range of wavelengths of light than either pigment could on its own. Other pigments, such as carotenoids and phycobilins, also have different absorption spectra. This allows plants to absorb a wider range of wavelengths of light, which is essential for the efficient conversion of light energy into chemical energy.
