Among the given options, option 4 is the incorrect pairing of plant hormones. Gibberellins are actually responsible for promoting bud and seed germination, rather than causing dormancy. They stimulate the synthesis of hydrolytic enzymes that break down stored starch into sugars, providing energy for growth and development. Gibberellins also promote elongation of stems and leaves. On the other hand, abscisic acid (option 1) is responsible for regulating transpiration and closing stomata in response to water stress. Auxins (option 2) are responsible for apical dominance, which means they inhibit the growth of lateral buds and promote the growth of the main shoot. Cytokinins (option 3) are responsible for delaying senescence or the aging of plant tissues by promoting cell division and growth.
