Solution
The correct option is A Chitin Cell wall is a tough, rigid layer that surrounds some types of cells. The cell wall is a characteristic feature to cells of plants, bacteria, fungi, algae, and some archaea. It is located outside the cell membrane. Cell wall composition varies from species to species and also depends on the developing stage of the organism. Protozoans and animals do not have a cell wall. In fungi, cell walls are made chitin.
