The aircraft OBI has a CRS of 060°, displaying TO and RIGHT TURN indications.
The TO indication places the aircraft's Radial on the OPPOSITE side of the VOR to the Selected Course of 060°, i.e. its Reciprocal Radial = 240°.
On a 2 dot HSI, a RIGHT TURN by 2 x dots (=10°) when going TO the beacon places it to the left of the 240° radial = 250° Radial.
The reciprocal of 250° TO the beacon, ie. the QDM, = 070°.
The QDM to the beacon = 070° M, which is always indicated by the RMI at the head of the needle.
The aircraft is on a heading of 010° M., therefore for Relative Bearing:
HDG + RB = QDM
RB = QDM - HDG
RB = 070° - 010°
RB = 060°
The only RMI indicating a QDM of 070° is B, which also shows a Relative Bearing of 060°
