Answer:

B.

Why might the presence of kudzu make it difficult for other plants to compete for resources?
Bingel [31]

Answer:

Kudzu kills trees and other plants by smothering and choking them with its fast-growing vines, and as the heavy vines engulf trees or shrubs their weight can actually break or uproot trees. A kudzu vine can grow as much as a foot per day and sixty feet during a growing season.
