Would You Expect a Plant Growing at High Density (With

Would you expect a plant growing at high density (with many close neighbors) to have higher or lower allocation to defense than one growing at low density?

A) Allocation to defense would be similar in both environments because it depends on soil type, not plant density.
B) Allocation to defense would be higher under high plant densities because losing any leaves to herbivores might lead to overtopping by neighbors.
C) Allocation to defense would be higher for plants at low density because such plants would not have to allocate resources to growing tall in order to avoid overshading.
