Question

one piece of evidence for the endosymbiotic theory is that...
prokaryotic cells came after eukaryotic cells
chloroplast have their own dna
mitochondria can make atp
eukaryotic cells

Explanation:

The endosymbiotic theory suggests that mitochondria and chloroplasts were once independent prokaryotes that were engulfed by a host cell. Chloroplasts having their own DNA is evidence as it indicates they were once separate organisms, similar to how bacteria have their own DNA. Prokaryotes came before eukaryotes, not after. Mitochondria making ATP is a normal function and not unique evidence for endosymbiosis. The option "Eukaryotic cells" is too general.

Answer:

Chloroplast have their own DNA
