C.
Acid is a chemical compound that when dissolved in water gives a solution with H+ ion. A base is that donates electrons, accept protons or release hydroxide (OH-) ions.
As there are two answers are right (A&C) but if it's single correct type question then C is more preferred answer.

Part A Which of the following statements accurately describes bacterial cell walls? In bacteria with acid-tast cell walls, the carboxylic acid in the walls forms a layer outside a thin layer of hydrophilic polypeptides. The cell walls of gram-negative bacteria contain many more layers of peptidoglycan than those of gram-positive bacteria. In gram-negative bacteria, the thin layer of peptidoglycan is surrounded by an outer membrane made of phospholipids, lipopolysaccharides, and proteins Gram-negative bacterial cell walls contain teichoic acids, whereas the...
