Prokaryotic cells are the primitive cells, which have disorganized nucleus. They do not have a nuclear membrane. These cells are devoid of membrane-bounded organelles. They are not specialized and lack division of labor. These are unicellular where a single cell performs all the functions e.g., bacterial cell.
Hence the correct option is A.
