Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Members of Rhodophyceae (red algae) contain chlorophyll-$a, d, r$ -phycoerythrin, rphycocyanin $\alpha$ and $\beta$-carotene pigments. So, it belongs to this group. Members of Chlorophyceae (green algae) contain chlorophyll- $a, c, \beta$-carotene pigments. Members of Bacillariophyceae (diatoms) contain chlorophyll- $a, c, \beta$-carotene, ecarotene pigments. Members of Cyanophyceae (cyanobacteria, blue-green algae) contain chlorophyll-$a, c$-phycocyanin, $c$-phycoerythrin, $\beta$-carotene pigments.

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.
