Oxidation typically doesn't happen in this acid-carbonate reaction for your level.
So the iron(II) ion stays as iron(II).
2HNO3 + FeCO3 → Fe(NO3)2 + CO2 + H2O

Always balance in this order, which works for all equations that involve ionic compounds:
1. Metal or positive ion on the right
2. Negative ion next to item 1) above
3. All other substances that have not been balanced.
This is illustrated for part d. Added an extra part e) for reference.
