$Mg + \text{dil. } HNO_3 \longrightarrow$

(B) The reactions are as follows:$1$. $2Mg + CO_2 \longrightarrow 2MgO + C$ ($MgO$ is formed).$2$. $Mg + 2HNO_3 \text{ (dil.)} \longrightarrow Mg(NO_3)_2 + H_2$ ($MgO$ is not formed; $Mg(NO_3)_2$ is formed).$3$. $2Mg + 2NO \xrightarrow{\Delta} 2MgO + N_2$ ($MgO$ is formed).$4$. $3Mg + B_2O_3 \longrightarrow 3MgO + 2B$ ($MgO$ is formed).Therefore,the correct option is $B$.
