In the double-slit experiment with light,
 
  A) the impact point of each photon cannot be predicted, and neither can the overall pattern of impact points.
  B) the impact point of each photon cannot be predicted, but the overall pattern can be predicted.
  C) the impact point of each photon can be predicted, but the overall pattern of impact points cannot be predicted.
  D) the impact point of each photon can be predicted, and so can the overall pattern of impact points of a large number of photons.

Question 2
