(B) The $IAA$ (auxin) is synthesized in the coleoptile tip and moves downwards through polar transport. For $IAA$ to collect in an agar block,the block must be placed in contact with the base of the coleoptile tip so that the auxin can diffuse into it. In option $B$,the coleoptile tip is placed directly on top of the agar block. As auxin is produced in the tip and moves basipetally (downward),it will accumulate in the agar block placed beneath it. Therefore,the correct arrangement is the one where the tip is placed on the agar block.

Which arrangement of an agar block on an oat coleoptile would result in $IAA$ collecting in the agar?
