Answer:
I would probably guess B.
Step-by-step explanation:
because the first row is x + 2 = y,
the second row is x + 3 = y,
the third is x + 4 = y,
the fourth is x + 6 = y,
so there is no pattern, therefore is is not D.
For A, the ratios are equal, but this is not the case for 4/7, so it can't be A.
C doesn't make sense, because some pairs are simplified, like the first two, but the last two are not.
So, you can make your own choice.
