La opcion d es la correcta, si observas en la gráfica esta intercepta al eje x en -1,5 y es allí donde y=0

It's the option d, remember that when you set an equation equal to zero, you're looking for the zeros and that graphically it's the intersection with the X Axis. I can see it is approximately x=-1,5.
