The statement that does not support the endosymbiotic theory would be the one that says mitochondria and chloroplasts are much larger than prokaryotic cells.
The endosymbiotic theory postulated that some organelles (mitochondrion and chloroplast) found in eukaryotic cells evolved from prokaryotic bacteria through a symbiotic interaction.
This is because the 2 organelles behave like independent organisms (prokaryotic) on their own with their own genome that seems similar to that of bacteria, ability to reproduce as well as having their own ribosomes.
Hence, that mitochondrion and chloroplasts are larger in size than prokaryotic cells is not one a point that can be used to support the endosymbiotic theory.
