This cell part uses digestive enzymes to break down worn out cell parts and other waste.
A
Lysosome
B
Mitochondria
C
Peroxisome
D
Vacuole
Explanation: 

Detailed explanation-1: -Lysosomes. In animal cells, the lysosomes are the cell’s “garbage disposal.” Digestive enzymes within the lysosomes aid the breakdown of proteins, polysaccharides, lipids, nucleic acids, and even worn-out organelles.

Detailed explanation-2: -Lysosomes are membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers-proteins, nucleic acids, carbohydrates, and lipids.

Detailed explanation-3: -For this task, they rely on an organelle called the lysosome, which works like a cellular stomach.

Detailed explanation-4: -In this regard, the lysosomes recycle the cell’s organic material in a process known as autophagy. Lysosomes break down cellular waste products, fats, carbohydrates, proteins, and other macromolecules into simple compounds, which are then transferred back into the cytoplasm as new cell-building materials.

Detailed explanation-5: -Lysosomes are found in nearly every animal-like eukaryotic cell. They are so common in animal cells because, when animal cells take in or absorb food, they need the enzymes found in lysosomes in order to digest and use the food for energy. On the other hand, lysosomes are not commonly-found in plant cells.
