Answer:
B
Solution:
F.W. Went isolated the auxins from theAvena coleoptiles. Auxins promote apical dominance by inhibiting the growth of lateral buds. Auxins promote flowering in plants like pineapple as it is a growth-promoting hormone-like cytokinin. Auxins do not affect the cytokinin level negatively as they are not antagonistic in function.
