Answer: The answer is C.
ok, in the traditional notation, a pair of numbers x and y is represented as: (x,y)
And the pairs in the table written in this notation are the next ones:
(1,2) , (2,4) , (3,3) and (4,2)
so the only option that is in the table is the option c = (4,2), while neither of the other options show in the table.
