Solution
The correct option is A GA3
Farmers in Asia were well aware of a disease of rice plants called bakane disease, which is also known as foolish seedling disease in Japan. Infected plants would grow excessively taller than the rest of the rice in the paddy, fall over, and be unharvestable. This disease was found to be caused by one fungus, called as Gibberella fujikori. Work on this physiology problem of Japan occurred in 20th century. Scientists in 1950s rediscovered this work and extracted a range of chemicals that elicit the growth response in seedlings. These are now known as gibberellins. Since that time, close to 100 slightly different gibberellins have been identified chemically.
