Answer 1

Answer: (A)

Gibberellins are growth promoting phytohormones. Gibberellins promote stem elongation in many plants. The application of this hormone causes an increase in the internodal regions which enhances the rosette formation in the leafy vegetables. This process is known as bolting which is commonly seen in the cabbage plants.

Thus, the correct answer is option A.
