Vedclass · Answer

(B) The abscission layer is a specialized zone of cells that forms at the base of leaves,flowers,or fruits,leading to their detachment from the plant body.Auxin is a plant hormone that inhibits the formation of the abscission layer and prevents premature leaf or fruit drop.When the concentration of auxin decreases in the plant tissues,the inhibitory effect is removed,which promotes the formation of the abscission layer.Therefore,a decrease in auxin concentration is the primary trigger for the formation of the abscission layer.
