When an acid reacts with water, it donates a proton (I), and water acts as a base (III) by accepting the released proton. This forms hydronium ions (H3O+), not hydroxide (V). Therefore, statements I, III, and IV are correct, making choice D the best answer. Statement II is not correct as water itself does not donate a proton but can accept it to form the hydronium ion.
