Solution

The correct option is B
They have their own DNA and ribosomes.

Mitochondria and chloroplasts have their own DNA and ribosomes. This is due to their evolutionary origin as primitive prokaryotes. They eventually became a part of the eukaryotic cell. They are semi-autonomous as they can replicate independently and produce their own RNA and proteins.
