Solution
The correct option is A Gibberellic acid-Leaf fall
Gibberellins are a kind of promotory PGR. These also delay senescence. Thus, the fruits can be left on the tree longer to extend the market period.
Auxins hormone are derived from indole-3-acetic acid (IAA). The plant hormone auxin is well known to stimulate cell elongation via increasing wall extensibility.
Abscisic acid (ABA) acts as a general plant growth inhibitor and an inhibitor of plant metabolism. ABA stimulates the closure of stomata and increases the tolerance of plants to various kinds of stresses.
Cytokinins have specific effects on cytokinesis. It helps to produce new leaves, chloroplasts in leaves, lateral shoot growth and adventitious shoot formation.
So, the correct matched pair is "option C"
