(B) Let us analyze the reaction of each compound with $HCl$:$1$. $Na_2CO_3 + 2HCl \rightarrow 2NaCl + H_2O + CO_2$ (Produces $1$ oxide: $CO_2$)$2$. $NaNO_2 + HCl \rightarrow NaCl + HNO_2$ (Further decomposes to $H_2O + NO + NO_2$. Produces $2$ oxides: $NO$ and $NO_2$)$3$. $Na_2SO_3 + 2HCl \rightarrow 2NaCl + H_2O + SO_2$ (Produces $1$ oxide: $SO_2$)$4$. $NaHCO_3 + HCl \rightarrow NaCl + H_2O + CO_2$ (Produces $1$ oxide: $CO_2$)Comparing the products, $NaNO_2$ produces $2$ oxides ($NO$ and $NO_2$), which is more than the others.
