(B) The initial moles of $A$ and $B$ are equal,i.e.,$n_A = 2$ and $n_B = 2$. According to the stoichiometry of the reaction,$2 \ mol$ of $A$ react with $1 \ mol$ of $B$. Since $A$ is consumed at a faster rate than $B$ to reach equilibrium,the remaining concentration of $A$ will be less than the remaining concentration of $B$. Therefore,at equilibrium,$[A] < [B]$.
