Solution
The correct options are
A Abscisic acid
B Ethylene
D Auxins
Primarily, aging and the dropping of leaves are controlled by the plant growth hormone named abscisic acid (ABA). It also helps to control the dormancy of the seeds and to sustain the plant in adverse conditions. Ethylene is a gaseous hormone which helps in the ripening of fruits. Auxin are hormones that promote cell elongation. However, an excess amount of ethylene and auxins cause the dropping of leaves and fruits as well.
