When a xerographic copier first applies electric charges to the surface of its photoconductor, it does so in the dark. The reason for applying these charges in the dark is that light exposure would
A) allow the charges to flow through the photoconductor so that they wouldn't accumulate on its surface.
B) release magnetic poles that would cancel the electric charges.
C) cause the magnetic poles to move, generating electricity that would neutralize the electric charges.
D) expand the coherence of the waves and prevent the charges from forming a real image on the surface.
