Refer to the figure, which shows a fungal interaction with a photosynthetic cell. Which statement is not a potential explanation for the scenario shown?
A) The fungus and photosynthetic cell have joined together in a symbiotic association to form a lichen.
B) The fungus has formed haustoria that push directly against the plant plasma membrane in order to absorb nutrients secreted from the plant cell.
C) The fungal hyphae are ectomycorrhizae and have entered the plant cell in order to provide nitrogen in exchange for carbon compounds.
D) A parasitic fungus has entered a leaf through a stoma and is leaching nutrients from the plant cells through specialized structures that form from its hyphae.
E) The fungal hyphae are part of an arbuscular mycorrhizal network in which the fungus provides phosphorus to the plant in exchange for carbon compounds.

None of the structures or interactions depicted in the figure suggest that the fungus is an ectomycorrhizal, which specifically grow around the outside of the plant root and do not enter the plant cell.
