None of the above

Detailed explanation-1: -The inner membrane creates two compartments. The region between the inner and outer membrane, called the intermembrane space, is largely continuous with the cytosol, while the more sequestered space inside the inner membrane is called the matrix.
Detailed explanation-2: -The inner membrane forms invaginations, called cristae, that extend deeply into the matrix. The cristae define the third mitochondrial compartment, the crista lumen. The crista membranes contain most, if not all, of the fully assembled complexes of the electron transport chain and the ATP synthase (Fig. 2).
Detailed explanation-3: -The space enclosed by the inner chloroplast membrane is called the stroma. Chloroplasts replicate giving rise to new chloroplasts as they grow and divide. They also have their own DNA and ribosomes.
