Answer- (3) Cyanobacteria

Cyanobacteria are also known as Cyanophyta, are a phylum consisting of free-living photosynthetic bacteria and the endosymbiotic plastids, a sister group to Gloeomargarita, that are present in some eukaryotes. They commonly obtain their energy through oxygenic photosynthesis.[4] The oxygen gas in the atmosphere of earth is produced by cyanobacteria of this phylum, either as free-living bacteria or as the endosymbiotic plastids.[5] The name cyanobacteria comes from the color of the bacteria (Greek: κυανός, romanized: kyanós, lit. 'blue').[6][7] Cyanobacteria, which are prokaryotes, are also called "blue-green algae",[4][8] though some modern botanists restrict the term algae to eukaryotes.[9] Cyanobacteria appear to have originated in freshwater or a terrestrial environment.[10]
