    That means they are asking you which of the following is more acidic than basic. H2O cannot be, because it can be neutral, a pH 7, meaning equal amounts of H3O and OH are there. NaOH when dissociates forms Na+ and -OH, that is forms a basic solution, with -OH greater than H3O. NaCl is considered to be a neutral salt, that is , when it dissociates, in forms pH7, which is equally balanced between acid and base. Therefore, the answer relies on HCLO4, Hyperchloric acid, which when dissciates forms H+ and ClO4-, both of these ions are highly concentrated with H+ rather than -OH. Hope it helped.
