4. A conductor is placed inside a non-constant electric field.

(A) The presence of the conductor zeroes out the electric field both inside and outside the conductor.

(B) The electric field outside the conductor is unaffected, but vanishes inside the conductor.

(C) The electric field inside the conductor will eventually become constant throughout the conductor but not necessarily 0, depending on how much charge is on the conductor surface.

(D) The electric field is 0 everywhere inside the conductor. Outside the conductor the electric field is distorted by the conductor.

(E) The conductor has no effect at all because it is not an insulator
