Solution

The correct option is D Induces parthenocarpy
The portion of a stem between the level of insertion of two successive leaves or leaf pairs is called an internode. The main job of gibberellin is to promote growth of the internodes by cell elongation.
Gibberellins are also capable of inducing parthenocarpy which means production of fruits without the fertilisation of ovules.
