Following are the some statement . Choose the correct one?
a. Primary Lysosomes are also called storage granules, protolysosomes or virgin lysosomes. Primary lysosomes are newly formed organelles bounded by a single membrane and typically having a diameter of 100 nm. They contain the degradative enzymes which  participate in digestive process. 
b. Heterophagosomes are also called heterophagic vacuoles, heterolysosomes or phagolysosomes. Heterophagosomes are formed by the fusion of primary lysosomes with cytoplasmic vacuoles containing extracellular substances brought into the cell by any of a variety of endocytic processes.
c. Autophagosomes are able to digest intracellular structures including mitochondria, ribosomes, peroxisomes and glycogen granules.
