Dieldrin, an insecticide, contains C, \( \mathrm{H}, \mathrm{Cl} \) and \( \mathrm{O} \). Combustion of \( 29.72 \mathrm{mg} \) of Dieldrin gave \( 41.21 \mathrm{mg} \mathrm{CO}_{2} \) and \( 5.63 \mathrm{mg} \) of \( \mathrm{H}_{2} \mathrm{O} \). In a separate analysis \( 25.31 \mathrm{mg} \) of Dieldrin was converted into \( 57.13 \mathrm{mg} \mathrm{AgCl} \). What is the empirical formula of Dieldrin ?
(a) \( \mathrm{C}_{6} \mathrm{H}_{4} \mathrm{Cl}_{3} \mathrm{O} \)
(b) \( \mathrm{C}_{8} \mathrm{H}_{8} \mathrm{ClO} \)
(c) \( \mathrm{C}_{12} \mathrm{H}_{8} \mathrm{Cl}_{6} \mathrm{O} \)
(d) \( \mathrm{C}_{6} \mathrm{H}_{4} \mathrm{Cl}_{3} \mathrm{O}_{2} \)
