Degradation of JAZ proteins occurs via:
26S proteasome (C) is correct here. This is core Jasmonic acid: once you know the definition or pathway step, 26S proteasome is the clear fit. The wrong ones are A) Lysosome; B) Autophagy; D) Peroxisome. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.
