Which statement best supports the theory that eukaryotic cells evolved through endosymbiosis?
A. Eukaryotic cells can eat prokaryotic cells by engulfing them with
cell membranes.
B. All prokaryotic cells are covered by a stiff cell wall that protects
them.
C. Their chloroplasts contain DNA that is similar to that of
prokaryotes.
D. Chains of amino acids form inside tiny bubbles filled with organic
molecules.

Their chloroplasts contain DNA that is similar to that of

prokaryotes

Explanation:

This is based on the theory that the membrane bound organelles of chloroplast and mitochondria  which are peculiar to Eukaryotas evolved from bacteria by endosymbiosis. Thus bacteria contain the DNA of these organism Evidently, these organism (Eukaryotas) must have cohabited  with bacteriA some time ago
