A gaseous hydrocarbon gives upon combustion, \(0.72 \mathrm{~g}\) of water and \(3.08 \mathrm{~g}\) of \(\mathrm{CO}_{2}\). The empirical formula of the hydrocarbon is
(a) \(\mathrm{C}_{2} \mathrm{H}_{4}\) (b)) \(\mathrm{C}_{3} \mathrm{H}_{4}\) (c) \(\mathrm{C}_{6} \mathrm{H}_{5}\) (d) \(\mathrm{C}_{7} \mathrm{H}_{3}\)
