The lower the pH, the greater the concentration of hydrogen ions (this is one of the definitions of an acid: a substance that increases the hydrogen ion concentration in water). So the answer here would be the one denoting the highest pH value, since that would indicate the smallest concentration of hydrogen ions.

That would be the substance with a pH of 11.2. Thus, the second answer choice here would be correct.
