These organelles contain digestive enzymes which destroy worn out parts of a cell or bacteria.

• A. Nucleus
• B. Vacuoles
• C. Lysosomes
• D. Golgi Apparatus

Answer: (C)

Digestive enzymes that break down waste and invaders are housed in lysosomes. These are membrane-bound sacs filled with hydrolytic enzymes that carry out intracellular digestion and recycling. They digest worn-out parts of the cell through autophagy and also destroy bacteria taken up by the cell through phagocytosis. The enzymes work best in the acidic environment inside the lysosome, and these organelles can fuse with vesicles containing material to be digested. This role is distinct from the nucleus, which stores DNA and controls cell activities; vacuoles, which mainly store substances; and the Golgi apparatus, which modifies, sorts, and packages proteins. So lysosomes are the organelles that contain digestive enzymes and perform the described destruction and recycling tasks.
