Answer:
c.third pic
Step-by-step explanation:
In the given figures we have a parabola and a straight line. The line is touching the parabola at two points ,no point,one point and two points in the first ,second ,third and fourth figure respectively.
For the system of equations with one solution the two equations will touch at one point.
In the third graph the red line is touching the parabola at one point and hence represent a system of equations having one solution.
