The Figure Shows a Reaction Between Methane Gas (Natural Gas

The figure shows a reaction between methane gas (natural gas, CH₄) and oxygen to produce carbon dioxide and water. Is the diagram accurate, and if not, what is wrong with it, and how could it be fixed?

A) There are too many hydrogen atoms on the right-hand side of the reaction arrow. Remove one hydrogen atom from each water molecule.
B) There are too many oxygen atoms on the right-hand side of the reaction arrow. Remove one oxygen atom from the carbon dioxide.
C) The diagram is accurate as shown.
D) There are not enough carbon atoms on the left-hand side of the reaction arrow. Add another methane molecule on the left, and then another carbon dioxide molecule on the right of the arrow.
E) There are not enough oxygen molecules on the left-hand side of the reaction arrow. Add another oxygen molecule on the left of the arrow, and another water molecule on the right.
