The correct option is
A A- 3, B- 1, C- 5, D- 4, E- 2
Auxin plant hormone induces apical dominance. Apical dominance is the growth of the shoot apex of plant. It increases the height of the plant.
Cytokinins were first discovered in 1955 as promoters of cell division in the DNA of Herring sperm. Since, that discovery many different compound with cytokinin activity have been discovered, both natural and synthetic (diphenylurea).
Gibberellin induces the synthesis of
α-amylase in the aleurone layers. GAs are plant hormones that regulate growth and influence various developmental processes, including stem elongation, germination, dormancy, flowering, sex expression, enzyme induction and leaf and fruit senescence.
Epinasty is the downward bending of a leaf or other plant part, resulting from greater growth of the upper side than of the lower side.
Ethylene is the phytohormone which promotes epinastic movement in plants. It also promotes early ripening of fruits.
Abscissic acid promotes seed dormancy, inhibits seed germination, inhibits fruit ripening, induces stomatal closure, etc.
Thus, the correct answer is option A.
