Answer 1

Answer: (B)

Auxin was isolated by F.W. Went from tips of coleoptiles of oat seedlings. Skoog and Miller identified and crystallized the cytokinesis promoting active substances that they termed kinetin. E. Kurosawa reported the appearance of symptoms of the 'Bakane' (a foolish seedling disease in uninfected rice seedlings when they were treated with sterile filtrates of the fungus. H.H. Cousins confirmed the release of a volatile substance from ripened oranges that hastened the ripening of stored unripened bananas.
