It appears
that the examiner has got somewhat confused here.
The front
end of the RMI Pointer indicates the QDM to the VOR, which is the Magnetic
Bearing TO the station.
The QDM is
also the Radial (QDR) plus 180º.
Therefore,
either (b) or (c) could be correct.
The Radial
(QDR) is the Magnetic Bearing FROM the station.
If this
question comes up, please select "Radial plus 180º" but appeal it and
be sure to let us know.
