The Correct Option is D

Solution and Explanation

The red and blue biliproteins, called phycoerythrins and phycocyanins, respectively, are found in algae. They both are called phycobilins. The phycobilins are active in the transfer of light energy to chlorophyll for utilization in the process of photosynthesis. The phycocyanins and phycoerythrins effectively absorb light over range of wavelengths that cannot be absorbed by chlorophyll. Thus, they prevents chlorophyll from long and direct illumination and also from its photo oxidation.

Algae

An Algae is a term mentioning a group of photosynthetic eukaryotic organisms. It has chlorophyll and nucleus but no root, stem, leaves and many features like normal land plants. Algae is both unicellular (e.g. Euglenophyta) and multicellular (e.g. seaweeds). Algae do photosynthesis and help in oxygen production

Algae can live in various habitats like moist rocks, soils, water bodies (both freshwater and marine) and in some animals (e.g. Sloth). Unicellular Algae belong to the Protista Kingdom and Multicellular algae belong to the Plantae Kingdom, but formerly all algae are categorized under kingdom Plantae for their photosynthetic nature.
