Explanation Prokaryotes, such as bacteria, have a cell wall that provides structure and protection. This cell wall is made up of various components such as peptidoglycan, lipopolysaccharides, and other specialized sugars and proteins. Ribosomes are not a component of the cell wall, as they are in charge of protein production and are found inside the cell. Chitin is also not a component of a prokaryote's cell wall, as it is a structural component of the cell wall in some fungi and invertebrates, but not in prokaryotes. Therefore, the correct answer is B: Ribosomes.
