The correct option is A Anabaena
Chlorophylls a and b are the major types found in higher plants and green algae. Chlorophyll a, the photosynthetic pigment, is essential for photosynthesis in eukaryotes, cyanobacteria and prochlorophytes. Anabaena, being cyanobacteria and euglena being a photosynthetic protozoan, have chlorophyll-a molecules.
