(D) $1$. Sodium bicarbonate $(NaHCO_3)$ is a weak base.$2$. Carboxylic acids $(-COOH)$ are acidic enough to react with $NaHCO_3$ to release carbon dioxide $(CO_2)$ gas.$3$. The evolution of $CO_2$ gas causes brisk effervescence.$4$. The reaction is: $R-COOH + NaHCO_3 \rightarrow R-COONa + H_2O + CO_2 \uparrow$.$5$. Therefore, the presence of the carboxylic acid group is indicated.
