How does the presence of different types of ribosomes inside a eukaryotic cell support the endosymbiotic theory?

A.)
The ribosomes inside the mitochondria and chloroplasts are different than those found in
prokaryotic cells indicating the origin of these ribosomes must be from eukaryotic cells.

B.)
All ribosomes inside the mitochondria and chloroplasts, and those on the endoplasmic
reticulum are different which indicates they originated in a eukaryotic cell.

C.)
All ribosomes inside the mitochondria and chloroplasts, and those on the endoplasmic
reticulum are identical which indicates they have a common origin.

D.)
The ribosomes inside the mitochondria and chloroplasts are the same as those found in
prokaryotic cells indicating the origin of these ribosomes must be from prokaryotic cells.
