(A) The correct answer is $A$ (Auxin). Auxins are known to prevent the premature abscission of young leaves and fruits by maintaining the integrity of the abscission zone. However,at higher concentrations or in specific physiological contexts,they can also promote the abscission of older,mature leaves and fruits by stimulating the production of ethylene,which triggers the formation of the abscission layer.

Which plant hormone prevents the premature shedding of leaves and fruits but promotes the abscission of older,mature leaves and fruits?
