The answer is B, the electrolysis of water. One cannot be the answer since the condensation of steam requires a loss of heat, an exothermic reaction. Numbers 2 and 3 cannot be correct either as they do not indicate energy in the chemical equation, and so it must be balanced throughout. Meaning that the only possible answer is B.
