The image above shows what happens when hydrochloric acid (HCl) and sodium hydroxide (NaOH) are mixed with water. Which statement below is true about both solutions? A. Both solutions contain solutes that do not dissolve completely in water.

B. Both solutions are saturated because they contain the maximum concentration of a solute dissolved in the solvent.

C. Both solutions will conduct an electric current because they both contain ions that can carry a charge.

D. Both solutions are acidic because they both contain hydrogen.
