Correct Answer: Option D
Explanation:
Auxins produced at the apex suppress the growth of lateral buds, maintaining apical dominance. Gibberellins induce rapid stem elongation or bolting in rosette plants before flowering. Cytokinins actually delay or prevent senescence (aging) of leaves by promoting nutrient mobilization, known as the Richmond-Lang effect. Therefore, statements 1 and 2 are correct, while 3 is false.
