Solution
The correct option is C Gibberellins Gibberellin is a plant hormone which is responsible for stem elongation by promoting cell division and elongation. They are responsible for increased internodal length in a plant.
Auxins cause cell elongation and cell differentiation while cytokinins promote only cell division.
Phycobilins are pigments found in cyanobacteria which capture the light energy for photosynthesis in them.
