The answer is C, because in the spectators frame the sprinter is going .99c and light is traveling @ 1.00c:
However in the frame of the runner, the light it STILL traveling @ 1c, the runner will say that the light beat him by a considerable margin. Also, this raises a topic of great confusion in Relativity and that is the idea of simultaneity...in Relativity there is NO SUCH THING as simultaneous events

circulate 'C' Off - mild isn't 'on the spot'. the two 'A' And 'B' look possible, yet I BEleive the respond is 'B'. As They the two initiate off on an identical 2d, the sunshine Beam Is Already Going swifter Than Ben, So It would not 'progressively' Come forward, It Already starts off forward. So Then It must be B.
