Extranuclear DNA is found in :
A Lysosome and chloroplast
B Chloroplast and mitochondria
C Mitochondria and lysosome
D Golgi and E.R.

Detailed Solution

Mitochondria and chloroplasts contain their own circular DNA, 70S ribosomes and machinery for protein synthesis; they are semi-autonomous.
Lysosomes, Golgi bodies and ER do not contain DNA.
So extranuclear DNA is found in chloroplasts and mitochondria.
