Binary fission occurs prokaryotic cells, and does not apply in this case, so A is not a correct answer.
Cells do not undergo $exual reproduction, so B is not a correct answer.
While eukaryotic cells generally do have ribosomes, it is possible to infer that the cells contain ribosomes. However, the ribosomes are not visible in the diagram, so E is not a correct answer.
