The balanced chemical reaction is:

C + H2O → CO + H2

We are given the amount of carbon to be used in this reaction. This will be the starting point of the reaction.

34 g C ( 1 mol C / 12.01 g C ) ( 1 mol  H2/ 1 mol C) (2.02 g H2 / 1 mol H2) = 5.72 g H2

Apparently, the correct answer is not in the given choices.
