The right answer is the membranes of mitochondria and chloroplasts.
It should be known that chloroplast and mitochondria membranes are not considered part of the endomembrane system, but they are thought to have evolved from it. This classification is due to the endosymbiosis of both organs.
Organelles of the endomembrane system include: double nuclear membrane, endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles, vesicles and endosomes.
