Final answer:
The cell membrane is responsible for regulating the transport of materials into and out of the cell. The option (B) is correct.
Step-by-step explanation:
The part of the cell responsible for regulating the transport of materials into and out of the cell is the Cell Membrane. The cell membrane is a selectively permeable barrier that separates the internal components of the cell from the extracellular environment.
It is composed of a phospholipid bilayer and various membrane proteins. Molecules can cross the cell membrane through passive transport, such as diffusion, facilitated diffusion, and osmosis, or through active transport, which requires energy. Therefore, option (B) is correct.
