The cell membrane help the cell by providing support and structure for the cell and regulating the transport of materials in and out of the cell. Thus, Option A and B are correct.
What is the function of plant cell membrane?
In plant cell the protoplasm is covered by a fine, elastic, bilayer and selectively semipermeable membrane called cell membrane. it is the second covering of plant cell.

It prevents movement of harmful substances and protects the protoplasm of the plant cell from the outside.
It also provides the barrier to separate between intracellular and extracellular environments.
