I would say Bacteria, option D.
thats because chloroplast were embedded in the plant cells by endosymbiosis. But i should check it also....

 

[IamJetLi]

its D. chloroplast and cyanobacteria are similar

 

[osims]

its definitly D, endosymbiont hypothesis says that the mitochondria and chloroplasts were once bacteria long long ago. mitochondria and chloroplasts also have circular DNA which is indicative of bacteria. They are also the same size as bacteria.

Joey2007 maybe you should read the books before starting to answer these questions it might help a little...wait i mean alot. good luck
