Solution
The correct option is C Fucoxanthin
- Fucoxanthin is a xanthophyll, found as an accessory pigment in the chloroplasts of brown algae and most other heterokonts, giving them a brown or olive-green color. It is the principal pigment of Phaeophyceae.
- Phycocyanin is a pigment-protein complex from the light-harvesting phycobiliprotein family, along with allophycocyanin and phycoerythrin. It is an accessory pigment to chlorophyll. All phycobiliproteins are water soluble, so they cannot exist within the membrane-like carotenoids.
- Phycoerythrin (PE) is a red protein-pigment complex from the light-harvesting phycobiliprotein family, present in red algae.
- Phycobilins are light-capturing pigments found in cyanobacteria.
Therefore, the correct answer is option C.
