Solution

The correct option is B Stem elongation
Auxin has various physiological effects in plants such as cell elongation, apical dominance, root initiation, prevention of abscission and inducing parthenocarpy.
Gibberellin has physiological effects on plants such as stem elongation, seed germination, breaking dormancy, elongation of internodes and inducing parthenocarpy.
Hence, stem elongation is due to Gibberellin.
So, the correct answer is 'Stem elongation'.
