Neutral compound : It is a compound that is formed by the combination of strong acid and strong base or weak acid and weak base.
As per question, KOH and LiOH are the examples of bases because they have ability of donating hydroxide ion, . KOH and LiOH are the strong base that are completely dissociate.
Hence, the correct option is, Bases.
