The correct option is A Darwin and Darwin - Gibberellic acid
Charles Darwin and his son first studied phototropism studying coleoptile of canary grass and oats. They suggested that phototropism was due to the chemical produced at the tip of a coleoptile. Went first discovered auxin as a plant growth hormone which is synthesized in the coleoptile tip. He also suggested that auxin senses the light and causes bending of stem due to the asymmetric growth of one side. Skoog and Miller discovered kinetin, a type of cytokinin in coconut milk. It promotes cell division. Gibberellic acid was first discovered by Eiichi Kurosawa from Gibberella fujikuroi fungus found in rice. H. H. Cousins first suggested that ethylene is the natural hormone produced by fruits of plants. Thus, the correct answer is option B.
