cell membrane
B
the cell wall
C
the Golgi apparatus
D
the nucleus
Explanation: 

Detailed explanation-1: -Peroxisomes-These collect and safely break down chemicals that are toxic to the cell.

Detailed explanation-2: -(3) The cell membrane forms a barrier that keeps all substances that might harm the cell from entering the cell. (4) The cell membrane controls the movement of molecules into and out of the cell.

Detailed explanation-3: -The cell membrane controls what substances pass into and out of a cell. Everything a cell needs, such as food particles, water, and oxygen, enters through the cell membrane. Waste products leave the same way. In addition, the cell membrane prevents harmful materials from entering the cell.

Detailed explanation-4: -The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.

Detailed explanation-5: -Nucleus. Known as the cell’s “command center, ” the nucleus is a large organelle that stores the cell’s DNA (deoxyribonucleic acid). The nucleus controls all of the cell’s activities, such as growth and metabolism, using the DNA’s genetic information.
