What statement is best supported by this information?

A.
Modern cells could exist without mitochondria and chloroplasts.
B.
Early prokaryotic cells engulfed eukaryotic cells, which later became mitochondria and chloroplasts.
C.
Early eukaryotic cells engulfed prokaryotic cells, which later became mitochondria and chloroplasts.
D.
Mitochondria and chloroplasts could exist outside of modern cells.
