The correct answer is B. Cell Walls
Explanation
Prokaryotic and eukaryotic cells are two types of cell that differ primarily because the eukaryotic has a cell membrane that separates the nucleus from the cytoplasm while the prokaryotic cell has all its content scattered in the cytoplasm without a defined nucleus. Another of its differences is its size, the prokaryotic cell measures between 1 and 10 microns while the eukaryotic measures between 10 and 100 microns. Despite their differences, they also have similarities, but the most important is that both have a cell wall that supports and protects the cell and allows intercellular communication. The correct answer is B. Cell Walls.
