Nitroalkanes and Alkyl Nitrite

An organic compound $\left(\mathrm{A}\right)$, on reduction, gives compound $\left(\mathrm{B}\right). \left(\mathrm{B}\right)$ on treatment with ${\mathrm{CHCl}}_3$ and alcoholic $\mathrm{KOH}$ gives $\left(\mathrm{C}\right). \left(\mathrm{C}\right)$ on catalytic reduction gives $\mathrm{N}-$methylaniline. What is compound $\mathrm{A}$?
