Relatively how many does each have? Like on a scale of 10, palisade would have 10, spongy would have maybe 5? and Guard cells would have like 2 or 3?

I'm pretty sure it's B. The jelly allows auxin to pass through the tip. And the foil prevents it. Though it'd be better if someone more experienced could confirm this :D
