Answer: D)The distance from Earth and mass of ISS exert negligible gravitational force on the astronaut.

Explanation:

The distance from Earth and mass of ISS exert negligible gravitational force on the astronaut. Gravity is a very weak force and varies with mass and the inverse square of distance. The astronaut's distance from Earth and the relative small mass of ISS result in gravitational force near zero.
