A) removing the lateral buds results in apical dominance under the influence of cytokinins.
B) removing the apical meristems results in less auxin, which results in more lateral branch growth.
C) removing the apical meristems makes less ethylene, which stimulates lateral branches to grow.
D) removing the apical meristems makes more auxin, which stimulates lateral branch buds to grow.
