$A$ and $H$ are the correct letters.

Work Step by Step

1. Identify all the salts: They are $A : K_2CO_3$ and $H: NaNO_2$. 2. Now, determine if they are acids or basics: $K_2CO_3:$ $K^+$: Insignificant acidity. $C{O_3}^{2-}$: Weak base. - $C{O_3}^{2-}$ is the stronger electrolyte, so, this salt is basic. $NaNO_2:$ $Na^+$: Insignificant acidity; $N{O_2}^-$: Weak base; - $N{O_2}^-$ is the stronger electrolyte, so, this salt is basic too.
