You Illuminate One Side of a Plant, but Then Dose

You illuminate one side of a plant, but then dose the whole plant with high levels of ethylene. Does the stem still bend toward the light?

A) No, ethylene suppresses elongation, and so would override the effect of higher auxin on the shaded cells.
B) No, ethylene suppresses elongation, and so would override the effects of higher auxin on the illuminated cells.
C) Yes, because even though ethylene suppresses elongation on both sides equally, higher auxin would lead to larger cells on the shaded side.
D) Yes, because even though ethylene promotes elongation on both sides equally, higher auxin would lead to larger cell sizes on the illuminated side.
