b) Gibberellins : perform the action same as that of the auxins (growth and distension), stimulate the flowering and the formation of the fruit and activate the seed germination.

c) Cytokinins : Rises the cellular division rate and together with the auxins help the growth and tissue differentiation, slow the aging of the plant.
