Which of statement below about black holes is not true?

A) A spaceship passing near a 10 solar-mass black hole is much more likely to be destroyed than a spaceship passing at the same distance from the center of a 10 solar-mass main-sequence star. B) We have strong observational evidence that black holes really exist. C) If you watch someone else fall into a black hole, you will never see the person cross the event horizon; you'll only see the person fade from view as the light he or she reflects (or emits) becomes more and more redshifted. D) If you fell into a black hole, you would experience time to be running normally as you plunged rapidly across the event horizon.
