Vedclass · Answer

(A) Apical dominance is the phenomenon where the main central stem of the plant grows more dominantly than the side (lateral) stems.This process is primarily controlled by the hormone $Auxin$.$Auxins$ are synthesized in the apical (terminal) buds and transported downwards.High concentrations of $Auxin$ in the terminal bud inhibit the growth of lateral buds,thereby maintaining apical dominance.Therefore,the correct answer is $A$.
