Choose one · Correct answer highlighted

Explanation

Propiconazole (B) is correct here. This is core Brassinosteriod: once you know the definition or pathway step, Propiconazole is the clear fit. The wrong ones are A) Glyphosate; C) Paclobutrazol; D) AMO-1618. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.
