There is never a single "correct" answer to this sort of problem; the more complicated the relationship, the more likely there are multiple relationships to be seen.
I do find that one of the choices in the list is fairly easy to obtain, but I can't be sure there isn't an equally reasonable way to get another. What I saw involves starting with the fact that all the choices are multiples of 5, so maybe they expect you to multiply the top number by some combination of the others. What multiples are there to choose from? Which corresponds to a pattern that also works in the bottom picture?
But this is not how mathematics works, and this sort of thing should not be taught as mathematics! Math is about provable relationships, not about imagining relationships based on insufficient data. So while the thinking I suggest may get you to the expected answer, don't imagine that it's really "correct".

Yes, that's the answer I saw.
