Expert Answer:

In the given graph horizontal axis showing current and vertical axis showing voltage.
let us draw a vertical line on the horizontal axis at some point. As the vertical distance increases from axis in this line, voltage increases.
Hence this vertical line first meets the graph-C, hence this corresponds to lowest voltage and hence lowest resitance.
hence graph C is for R2 (since R1>R2)
vertical line meets the graph-A last, hence highest voltage, highest resistance. Hence graph-A corresponds to (R1+R2)
hence graph-B corresponds to R1
hence the option " (D)series combination, R1, R2 " is the correct answer
