Answer:
The correct answer is
C. Surface craters
The crater is not large enough to cause any permanent damage such as flooding, extinction for weather patterns. Since it is falling from the sky at such a great velocity it will of course leave a little "dent" in earths surface. This is short term because overtime the crater will fill in an become flat ground.
Hope this helps!
