Root can absorb minerals from the soil when they are in

Answer: Option A

The root can absorb minerals from the soil when they are in a Solid state.
In plants, the entrance portal for mineral uptake is usually through the roots. Some mineral ions diffuse in between the cells.
Plants absorb minerals in the ionic form: of nitrate (NO₃^-), phosphate (HPO₄^-), and potassium ions (K⁺); all have difficulty crossing a charged plasma membrane.
Mineral nutrient concentration in roots maybe 10,000 times more than in surrounding soil. During transport throughout a plant, minerals can exit the xylem and enter cells that require them.
