Question
GA signaling activates which transcription factor for α-amylase?
Explanation
GA-MYB (C) is correct here. This is core Gibberellins: once you know the definition or pathway step, GA-MYB is the clear fit. The wrong ones are A) ARF; B) HY5; D) PIF. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.
