Explanation:

Justification: Statement 2: Gibberellins (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.
Statement 3: They promote cell division, or cytokinesis, in plant roots and shoots.
