Text Solution

Verified by Experts

The correct Answer is:
A
Xanthophylls (=Carotenois) are oxygen containing derivatives of carotenes, e.g., `C_(40)H_(56)O` (cryptoxanthin), `C_(40)H_(56)O_(2)` (lutein, zeaxanthin) Yellowish colour of autumnal follage is due to lutein. The characteristic xanthophyll of brown algae is fucoxathin `(C_(40)H_(56)O_(6))`
