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.

In Neurospora, the mutant stp exhibits erratic stop-and start growth. When a female of stp strain is crossed with a normal strain acting as a male, all progeny individuals' showed stp mutant phenotype. However, the reciprocal cross resulted in all normal progeny, individuals. These results can be explained on the basis of

A. Uniparental gene contribution

B. Nuclear inheritance with concept of dominance

C. Sex link character

D. stp mutation may be located in chloroplast DNA
