I hate these style of questions - I hope this is not a real exam question for a 21st century pilot licence, although I fear it may be.
1. The Q code was deprecated when VHF voice communications replaced morse code, and should not generally be used, ruling out answers A and B.
2. Answer C is a trick answer, since radials always run "from" the station, so the radial is on the tail, but nobody cares about that distinction in the real world either.
The great thing about the RMI is that interpretation of it is completely natural - the pointer points at the station. That's all you need to know.
Rant Over. Thanks for listening.
(In the 1950's, the answer they were probably looking for was A).
