(B) Acetic acid $(CH_3COOH)$ is a weak acid that dissociates as: $CH_3COOH \rightleftharpoons CH_3COO^{-} + H^{+}$.When sodium acetate $(CH_3COONa)$ is added,it provides a high concentration of $CH_3COO^{-}$ ions.According to the common ion effect,the equilibrium shifts to the left,which decreases the concentration of $H^{+}$ ions $([H^{+}])$.Since $pH = -\log[H^{+}]$,a decrease in $[H^{+}]$ leads to an increase in the $pH$ value.

When sodium acetate is added to a solution of acetic acid,its $pH$ value:
