F. W. Went in 1928 used tip of Avena coleoptile. He removed the tip of Avena coleoptile and placed in on the agar block for the definite measured amount of time. Then this agar block was placed asymmetrically on the stump, this showed a positive curvature.
When this agar block was placed centrally on the stump then the growth of the coleoptile was found to be renewed. He named this growth promoting substance or hormone as auxin.
He also noticed that curvature in Avena coleoptile is proportional, to the amount of auxin in agar block. Hence, option A is correct.
