Cytokinin

KISS ME DEADLY (KMD) proteins regulate cytokinin response by:

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

Cytokinin

Type-A ARRs mainly function as:

Answer: B) Negative feedback regulators. For Cytokinin, remember the key idea and you’ll land on this option; the distractors usually swap cause and effect or confuse similar terms. Avoid: A) Positive regulators; C) Receptors; D) Kinases. Name the process first, then pick the option that describes it — don’t reverse cause and effect.
