A) to support a cell

Explanation:

A Cell membrane is a thin semi-permeable membrane that surrounds the cytoplasm of a cell, enclosing its contents. The membrane also gives a cell its shape and enables the cell to attach to other cells, forming tissues. The cell membrane also serves as a base of attachment for the cytoskeleton in some organisms and the cell wall in others. Thus, it helps to support the cell and maintain its shape. The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells. The basic function of the cell membrane is to protect the cell from its surroundings.
