Mitochondria are separated into two compartments, the matrix and the intermembrane space, by their inner and outer membranes. How does the presence of two compartments contribute to the function of mitochondria?

A) The double- membrane feature of mitochondria is what enables them to glycosylate proteins.
B) The two compartments permit different but complementary functions to be accomplished in the organelle.
C) It enables mitochondrial DNA and ribosomes to remain separated from the functional compartment of the mitochondria.
