The formation of water from \[{{H}_{2}}(g)\] and \[{{O}_{2}}(g)\] is an exothermic reaction because       [MP PMT/PET 1988]

A)                 The chemical energy of \[{{H}_{2}}(g)\] and \[{{O}_{2}}(g)\] is more than that of water

B)                 The chemical energy of \[{{H}_{2}}(g)\] and \[{{O}_{2}}(g)\] is less than that of water

C)                 Not dependent on energy

D)                 The temperature of \[{{H}_{2}}(g)\] and \[{{O}_{2}}(g)\] is more than that of water
