Solution
The correct option is D Gibberellin Gibberellin hormone regulates the growth and elongation of the stem. It is able to promote the internode elongation because of which the size of sugarcane stem increases. The stem is the edible part of sugarcane. Thus, spraying of gibberellin increases the growth of the consumable part and hence, yield gets increased.
