Solution
The correct option is D Both ferric and ferrous
Plants only need a tiny amount of iron to be healthy, but that small amount is crucial.
Plant roots absorb Fe from the soil solution most readily as ferrous ions (Fe2+) but in some cases also as ferric ions (Fe3+). The chemical nature of iron allows it to play an essential role in oxidation and reduction reactions, respiration, photosynthesis etc.
