These broaden the absorption and utilization of light:

Explanation

Carotenoids, which include carotenes and xanthophylls, are accessory pigments found in plants. They play a crucial role in broadening the range of light absorption beyond the wavelengths absorbed by chlorophyll alone. By capturing additional light energy, they enhance the plant's ability to perform photosynthesis efficiently. The incorrect options suggest individual pigments, which alone do not provide the broad spectrum of light absorption that is achieved by the combined effect of yellow and red-to-orange pigments.
