I agree...see Newton's 1st Law of Motion.

Wouldn't it depend on it's velocity? I think it's velocity would be different depending on the frame of reference it's viewed from, especially near the speed of light. In some frames of reference it even experiences an acceleration. Am I wrong?

The question doesn't mention an acceleration or frames of reference.  I think the intent is for the student to recognize that it will have a constant velocity absent any external forces.
