some protists have cell walls
All have some sort of membrane. Only some protists have cell walls, mostly algae.
c. a cell wall
The protective barrier of a cell is its cell membrane, also known as the plasma membrane. It surrounds the cell, providing structure and separating the cell's internal environment from the external environment. The cell membrane regulates the passage of substances in and out of the cell to maintain homeostasis.
Well, it depends on what type of cell you are talking about. If it's an animal cell, the outer covering would be the cell membrane. In a plant cell, the outermost one is the cell wall, then the cell membrane.
The outermost structure of a plant cell is a cell wall. Plant cells have cell walls for extra protection as they cannot move like animals and protists, whose outermost cell structure is the cell membrane, a thinner protective cover.
Animal cells have a cell membrane but do not have chloroplasts or a cell wall.
Either the cell membrane, or the cell wall. The cell membrane is most common in animals, and protists, whereas some monerans, and most plants and fungi have a cell wall.

yes, all protists do have a cell membrane

All cells have cell walls. The big difference is that plant cells have an additional layer of cell wall covering them.
