One gram sample of heptane, C7H16 is burned in excess of oxygen in a bomb calorimeter. The temperature of the calorimeter rises from 290 K to 298 K. If heat capacity of the calorimeter is 7 kJ/K, the enthalpy of combustion of heptane is
(a) 5472 kJ/mol
(b) 5234 kJ/mol
(c) 5400 kJ/mol
(d) 5600 kJ/mol
