C) Lysosome D) Vacuoles
 
Answer & Explanation Answer: C) Lysosome

Explanation:

Each lysosome is surrounded by a membrane that maintains an acidic environment within the interior via a proton pump. Lysosomes contain a wide variety of hydrolytic enzymes (acid hydrolases) that break down macromolecules such as nucleic acids, proteins, and polysaccharides. So, they are known as storehouse of digestive enzymes.
