Suppose a virtual particle-antiparticle pair appears just outside the event horizon of a black hole, and that each particle is the same distance from the center of the black hole. What will happen in this case?
A) Gravity from the black hole will attract the particle and repel the antiparticle, thus separating them. They will become real, and neither of them needs to enter the black hole.
B) Gravity from the black hole will attract the particle and repel the antiparticle, thus separating them. They will become real, and both of them will enter the black hole.
C) Gravity from the black hole will attract the particle and repel the antiparticle, thus separating them. They will become real, and the particle will enter the black hole.
D) The gravitational force from the black hole will cause the particles to move toward each other, and they will recombine without affecting the black hole.

Virtual particles typically recombine quickly without affecting their surroundings. If they appear just outside the event horizon, they are likely to recombine without either entering the black hole.
