(A) The $Avena$ $sativa$ coleoptile curvature test,also known as the $Avena$ curvature test,is a classic bioassay used to detect and quantify the presence of auxins.This test was developed by Frits Went in $1928$.In this experiment,agar blocks containing auxin are placed asymmetrically on the cut tip of $Avena$ coleoptiles.The auxin diffuses into the coleoptile,causing differential growth (more growth on the side with auxin),which results in the curvature of the coleoptile.The degree of curvature is proportional to the concentration of auxin present in the solution.

The presence of auxins in a solution can be tested by:
