When both water and salts are present is a solution and the cell needs water which process enables the cell to obtain the water without salt a. osmosis through a permeable membrane b. diffusion through a permeable membrane c. osmosis through a sempiermeable membrane d. diffusion through a nuclear membrane

The correct option is OSMOSIS THROUGH A SEMI PERMEABLE MEMBRANE.
Osmosis is defined as the process by which molecules of a solvent [water] are transported through a semi permeable membrane from the region of a lower solute concentration to that of higher solute concentration. The membrane is said to be semi permeable because it allows the water molecules to pass through but does not allow the salt molecules to pass.

No they’ve not done that
