Question

According to the special theory of relativity, physical laws are the same in frames of reference which ...

accelerate.

move at uniform velocity.

move in ellipses.

move in circles.

Answer 1

move at uniform velocity

Answer 2

Move at uniform velocity. Any differences in relative speed will cause some time dilation. In special relativity, the time dilation effect is reciprocal. That's a fancy way of saying that as observed from the point of view of any two clocks which are in motion with respect to each other it will always look to you (or your frame of reference) like the other guy's clock is running slower or faster.
