Answer to Question 1

Answer: C

Answer to Question 2

In large bodies, the gravitational forces are much larger than the elastic forces, so the body takes on a spherical shape (except for a slight oblateness due to rotation,) whereas in small bodies the elastic forces are much larger, so the bodies retain their shape.
