The choices are as follows:
h2o + 2o2 = h2o2
fe2o3 + 3h2 = 2fe + 3h2o
al + 3br2 = albr3
caco3 = cao + co2

The correct answers would be the second and the last option. The equations that are correctly balanced are:

 fe2o3 + 3h2 = 2fe + 3h2o
caco3 = cao + co2

To balance, it should be that the number of atoms of each element in the reactant and the product side is equal.
