Answer 2

Without gravity, all rocks and debris would lose masses and never accrete into a planet.

Answer: Option B

Explanation:

According to the well-known physicist James Overduin, the Earth would be nothing but a flat surface in the absence of gravity. Gravity provides weight to objects with which they attract towards the source i.e. the Earth and that's why it forms the circular shape.

If the universe and Earth would not have gravity, it would not curve and since gravity is considered as the curvature of space and time. There would be no matter and energy that cause it to curve.
