Cyanobacterium 
a division of microorganisms that are related to the bacteria but are capable of photosynthesis. They are prokaryotic and represent the earliest known form of life on the earth.

somy · Answer

Bacteria is prokaryote on its own

It is definitely not C or D, but I'm not sure that I agree with Somy.
The question is not asking about what cyanobacteria are.  It is asking what would result if a cell engulfed cyanobacteria in a form of endosymbiosis. 

The result would be a eukaryote that would be able to rely on the cyanobacterial endosymbiont to make its own food.
