It is believed that a black hole exists at the center of the Milky Way Galaxy.......

While the black hole is gigantic, we are not in danger of being sucked in because

A. black holes are not really as strong as described in science fiction.
B. the Earth’s magnetic field thwarts the pull of gravity from a black hole.
C. gas, dust and other interstellar material interfere with the pull of gravity.
D. we are located too far away from the center of the black hole to be susceptible.

d

I would say A and D. However, A requires a subjective assumption based on how 'sci-fi' attributes the power of black holes. Scientifically, D is the more correct answer, as gravity loses efficacy over distance. Remember the 'inverse square law' - i.e. twice as far, 4x less gravity, etc.
For example, many people don't seem to realize that 'if our Sun was turned into a black hole' (if the SAME MASS were condensed into the size of a grape), it would have THE SAME gravitational pull, the planets would continue on their paths just the same. Remember, it's the same mass, and mass determines gravitational pull.

The answer is D. You have to be near the event horizon to really be in danger of being sucked into a black whole. The event horizon is not a huge area and the Earth is light years away from the nearest black whole.

It would be D, but you must remember that black holes technically, are still theoretical.

D. we are located too far away from the center of the black hole to be susceptible.
