Two events that are simultaneous in one frame of reference will be:
A) simultaneous in all frames of reference
B) simultaneous in another frame that is moving in the opposite direction
C) simultaneous in another frame of reference that is moving in the same direction
D) simultaneous in the same frame of reference
E) simultaneous in another non-inertial frame of reference
I'm thinking "D" ..?
Yes, D, although it is a rather strange choice. All they are saying is "It is what it is".
