it might be D not 100% sure

anonymous · Answer

the function on X and Y are in the sequence that was originally formed so in my conclusion it mostly summed up to answer D

nikato · Answer

i think its B.
in order to have a function, every X must have a unique Y

B is the only answer that contains an x-coordinate that wasnt in the original points
