A light flash leaves a master clock at x = 0 at time t = -12 s, is reflected from an object a certain distance in the -x direction from the origin, and then returns to the origin at t = +8 s. From this information, we can infer that the spacetime coordinates of the reflection event are [t, x] =

A. [4 s, 20 s] B. [-4 s, -20 s] C. [10 s, -2 s] D. [2 s, -10 s] E. [-2 s, -10 s] F. Other (specify)
