Solution
The correct option is C Heterophagy Lysosomes are also called as heterophagous. Lysosome fuses with the food containing phagosome. They are also called acid hydrolases because these digestive enzymes usually function in acidic medium or pH of 4—5. The covering membrane of lysosomes keeps the hydrolytic enzymes out of contact from the cellular contents. It is itself protected from them by high glycosylation of its proteins and lipids. Thus Lysosomes help in digestion.
