Answer:
D. Acceleration in space and gravity on Earth have the same effects on objects.
Step-by-step explanation:
The answer is a major highlight of the theory of general relativity. The general relativity disproves a different effect on acceleration in space and gravity ( Newton's ideas). This is because gravity is not seen as force but a distortion that occur in space and time. Therefore, the effect of acceleration in space and gravity on earth are the same.
