Solution
The correct option is C IAA
Bioassay is a sensitive and specific test that determines the biological activity of hormones by measuring its effect on a specific part of plant material. There are various bioassays to determine the concentration of auxin hormone in plant such as avena coleoptile test, split pea stem curvature test, cress root inhibition test. The Avena coleoptile test is a bioassay for IAA (indole-3-acetic acid) that measures the angle of curvature of a decapitated coleoptile after placing an agar block containing auxin on one side.Thus, the correct answer is option C.
