Solution

The correct option is A Cyanobacterium
Red sea is one of the warmest, saltiest, and possibly reddest seas around the world, because of the presence of blooms of cyanobacteria namely Trichodesmium erythraeum. Trichodesmium blooms can appear brown when the bloom is healthy; green when the bloom is starting to decay; pink or red when certain pigments leak out of the cells. They are unique because it gets most of its nitrogen from the atmosphere. It has specialized structures that allow it to convert nitrogen gas into a usable form of nitrogen, ammonia. This process is called nitrogen fixation.
Thus, the correct answer is 'Cyanobacterium.'
