- AConcentrated phosphoric acid is a stronger oxidising agent than concentrated sulfuric acid.
- BConcentrated phosphoric acid is a stronger oxidising agent than iodine.
- CConcentrated sulfuric acid is a stronger oxidising agent than chlorine.
- DConcentrated sulfuric acid is a stronger oxidising agent than iodine.
