The correct option is C Both A and C
The endoplasmic reticulum is a system of membrane-lined channels found in all eukaryotes except mature erythrocytes. Membranes of the endoplasmic reticulum are thinner than most other cell membranes. Endoplasmic reticulum has three parts - cisternae, i.e., flattened sacs, tubules, i.e., branched network and vesicles. The endoplasmic reticulum is often connected with the outer membrane of the nucleus. It may also open at plasmalemma.
The Golgi complex is constantly being formed, changed, broken down and reformed. It has been variously described as being formed from the plasmalemma, nuclear envelope, annulate lamellae and the endoplasmic reticulum. It ha flattened sacs or cisternae; Small tubules and vesicles and Large vacuoles. Thus, the correct answer is option D.
