Correct option (b) Iysosomes
Explanation:
Lysosomes (or suicidal bags or cellular house keepers or scavenger of cell) are single membrane bound, spherical microbodies, filled with different types of acid hydrolases (digestive enzymes) working at pH ≤ 5 and can digest almost every type of organic matter except cellulose.
Primary lysosome (storage granules) unites with food vacuole (phagosome) forming secondary lysosomes (heterophagosomes or digestive vacuoles) which cause intracellular digestion (heterophagy).
