Which of the following statements is most closely associated with einstein's general theory of relativity?

being in an accelerated frame is indistinguishable from experiencing gravity.

mass is equivalent to weight.

the gravitational constant has the same value everywhere.

the gravitational force between any two objects is universal.

The answer is the first one. That's because the general theory of relativity is the thing experiencing whatever is experiencing relative to something else. The second answer is just plain wrong. The third answer is just a constant, and doesn't relate to experiencing anything. And the fourth answer is a force between two objects, and it has no second comparison. The first answer is how a subject experiences two different things.
