the table shows the relationship between the number of cups of cereal and the number of cups of raisins in a cereal bar recipe:

number of cups
of cereal number of cups of
raisins
8 2
12 3
16 4

maria plotted an equivalent ratio on the coordinate grid below:

a graph is shown. the title of the graph is cereal bars. the horizontal axis label is cereal in cups. the horizontal axis values are 0, 80, 160, 240, 320, 400. the vertical axis label is raisins in cups. the vertical axis values are 0, 10, 20, 30, 40, 50. a point is plotted on the ordered pair 80, 10.

which of these explains why the point maria plotted is incorrect?

a -if the number of cups of raisins is 80, then the number of cups of cereal will be 20.
b- if the number of cups of cereal is 80, then the number of cups of raisins will be 20.
c- if the number of cups of cereal is 80, then the number of cups of raisins will be 160.
d- if the number of cups of raisins is 80, then the number of cups of cereal will be 160.
