Answer:

C: The Fe is not balanced

Explanation:

The reaction expression is given as:

          Fe₂O₃   +   3H₂  →  Fe  +  3H₂O

The problem here is to find the specie that is not balanced.

                                                        Number of moles

Specie                               Reactant                                      Product

Fe                                              2                                                 1

O                                               3                                                3

H                                                6                                                6      

So, we see that Fe is not balanced.
