The most appropriate characteristic of a semi-permeable membrane is that
(a) it has minute pores.
(b) it has no pores.
(c) it allows the solute to pass through but not the solvent.
(d) it allows a solvent to pass through freely but prevents the passage of the solute.

An outermost envelope-like membrane or a structure, which surrounds the cell and its organelles are called the plasma membrane. It is a double membraned cell organelle, which is also called the phospholipid bilayer and is present both in prokaryotic and eukaryotic cells.
The plasma membrane is a selectively permeable membrane, which permits the movement of only certain molecules both in and out of the cell. It has minute pores called channels that allow the movement of particles in and out of the cell.
The correct option is (a).
The semipermeable membrane has minute pores
