I just had a test at school today for special relativity and had a question almost identical to the attached question. This question was taken from a 2008 exam and in the examiner's report they gave all 4 answers as correct (obviously they decided that it was a dodgy question). I told my teacher this during the test today and he just said to choose whatever answer I thought was right and give an explanation of why, so I chose C and D and said that C is correct because if they were not equal distances apart then the light rays would reach Nancy at different times and that D is correct because if the speed of light was not a constant then the light also would not reach Nancy simultaneously. What are your thoughts? (Note: It says "all observers" in option D, which is not correct because in reality 'c' can vary for non-inertial, however in the course structure of the physics course it states Einstein's 2nd Postulate saying "the speed of light has a constant value for all observers regardless of their motion or the motion
of the source", hence this is not a technicality that they're trying to trick us on.)
