The correct option is B Elongation of genetically dwarf plants
Gibberellin is a plant hormone which helps in growth of stem. It also brings about the rapid flowering in plants. It replaces the long day required for bolting in plants. It also helps in elongation of the internodes in such a way that dwarf plants overcome the genetic dwarfism.
