Which statement does einstein’s theory promote about space and time?
a. time, space, and the speed of light depend on reference frames.
b. time and space depend on reference frames, but the speed of light does not.
c. the speeds of light and space depend on reference frames, but time does not.
d. the speeds of light and time depend on reference frames, but space does not.

b). Time and space depend on reference frames, but the speed of light does not.

Explanation:

Einstein in his famous theory- The Theory of Relativity had mentioned about time and space which are based on reference frames. A reference frame is any type of standard point in space from where motion or rest of any object can be determined and measured. As such space and time can also be determined from a reference frame.
