Option D, leaves
Explanation:
The maximum concentration of zinc is accumulated both in the leaves and stem of corn and tobacco plants. But comparatively it is higher in the leaves than in the stem.
Zinc is a micro nutrient as it is required only in a small amount and it is found that plants will lesser zinc concentration dry out easily.
Also the relation between the zinc absorbed is linear to the accumulation of zinc in the leaves. Hence, the higher the zinc absorbed in the corn and tobacco plants, the higher is the zinc accumulating in the leaves.
Hence, option D is correct
