Combustion reaction

An organic compound $\mathrm{A}$ on heating with concentrated ${\mathrm{H}}_2{\mathrm{SO}}_4$ forms a compound $\mathrm{B}$ which on addition of one mole of hydrogen in presence of $\mathrm{Ni}$ forms a compound $\mathrm{C}.$ One mole of compound $\mathrm{C}$ on combustion forms two moles of ${\mathrm{CO}}_2$ and three moles of ${\mathrm{H}}_2\mathrm{O}$. Identify the compounds $\mathrm{A}, \mathrm{B}$ and $\mathrm{C}$ and write the chemical equation of the reactions involved.
