Applying Fungicides to Plants May Result in a Phosphorus Deficiency

Applying fungicides to plants may result in a phosphorus deficiency. What is the MOST likely explanation for this observation?

A) The fungicide destroys phosphorus transporters in the plasma membrane of root cells.
B) After fungicide is sprayed, plant cell walls impede the uptake of phosphorus to limit the amount of fungicide that enters the plant.
C) The fungicide blocks ATP synthesis, so phosphorus cannot be absorbed into plant cells.
D) The fungicide inhibits nitrogen fixation.
E) The fungicide destroys mycorrhizal symbionts.
