Solution

The correct option is A

Auxins


Avena curvature test is a bioassay for examining the activity of auxin. In 1928, Went developed a method of quantifying auxin. His results suggested that the curvatures of stems were proportional to the amount of auxin in the agar (Went, 1928). This test was called the avena curvature test. Much of our current knowledge of auxin was obtained from its applications.
