Which of the following statements about black holes is not true?

If you watch someone else fall into a black hole, you will never see him or her cross the event horizon. However, he or she will fade from view as the light he or she emits (or reflects) becomes more and more redshifted.
If you fell into a black hole, you would experience time to be running normally as you plunged rapidly across the event horizon.
All objects inside the event horizon of a black hole can never escape to reach infinity. But they may move radially away from the singularity for a certain finite distance before falling back towards it.
A black hole is truly a hole in spacetime, through which we could leave the observable universe.

Is D the false statement? A black hole is a gravity well so it somewhat has a bottom. Even if we fall inside the black hole and get out of sight, we are still within the boundaries of the observable universe?

For B, may I confirm that we would experience time normally as we fall into the black hole ourselves due to spaghettification (the stretching effect)? If we observe a clock/another person falling into the black hole, we would see the slowdown of time for them?

For C, is that any object would be able to move towards or away from the event horizon before passing the event horizon? After reaching the point of no return, any objects would fall one-direction straightaway into the singularity?

Many thanks!
