When equal moles of a weak acid and a strong base are added to water, the strong base will react completely with the weak acid and form its conjugate base. In this case, KOH will completely react with HCN to form KCN and water. KCN is the conjugate base of HCN and it is a strong base that will make the resulting solution basic. Therefore, the answer is B) basic.
