Vedclass · Answer

(A) Apical dominance is a phenomenon where the main central stem of the plant grows more dominantly than the side (lateral) buds. This process is primarily controlled by $Auxins$, specifically $Indole-3-acetic 	ext{ } acid$ $(IAA)$. $Auxins$ produced in the apical meristem inhibit the growth of lateral buds, thereby maintaining the dominance of the main shoot. Therefore, the correct option is $A$.

Select an appropriate plant hormone responsible for apical dominance from the following.
