Solution

The correct option is B Gibberellins
In the 19th century, Japanese farmers observed that the seedlings of rice were abnormally elongated due to infection of some fungus. This fungus was isolated, studied and named as Gibberella fujikori. The disease was termed as foolish seedling disease because during this infection the hormone gibberellic acid helps in stem elongation in plants.
Thus, the correct answer is option B.
