Small vesicles that digest materials in the cell using enzymes.
A
Ribosomes
B
Lysosomes
C
Nucleus
D
Mitochondria
Explanation: 

Detailed explanation-1: -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-2: -Lysosomes. Lysosomes are vesicles that contain digestive enzymes. They are only present in animal cells. They function as part of the cell’s recycling system and can also help initiate cell death.

Detailed explanation-3: -Lysosomes are membrane-enclosed compartments filled with hydrolytic enzymes that are used for the controlled intracellular digestion of macromolecules. They contain about 40 types of hydrolytic enzymes, including proteases, nucleases, glycosidases, lipases, phospholipases, phosphatases, and sulfatases.

Detailed explanation-4: -Lysosomes are small vesicles derived from the Golgi apparatus; they contain up to 40 acidic enzymes (hydrolases) at a pH 5. The membrane prevents the aggressive enzymes from destroying cellular structures.

Detailed explanation-5: -“Lysosomes are sphere-shaped sacs filled with hydrolytic enzymes that have the capability to break down many types of biomolecules.” In other words, lysosomes are membranous organelles whose specific function is to breakdown cellular wastes and debris by engulfing it with hydrolytic enzymes.
