Students perform an experiment using the setup shown in the figure. A sphere with uniform charge distribution on an insulating stand is placed a distance from parallel uncharged conducting plates separated by a fixed distance d. Points A and B are labeled.

Which of the following best explains how and why the charges will distribute in the plates?

The sphere will induce the net charge of the right plate to become negative, which will in turn induce the net charge of the left plate to become positive.
The sphere will initially induce the net charge of the right plate to become negative, but then electrons from the right plate will conduct to the left plate until the net charge of the right plate returns to zero.
The sphere will induce charge separation in the right plate, which will in turn induce charge separation in the left plate, and the net charges of the plates will remain zero.
The sphere will induce charge separation in the right plate, which will in turn induce charge separation in the left plate, and the net charge of the right plate will be slightly negative, while the net charge of the left plate will be slightly positive.
