Solution

R-configuration indicates that a clockwise circular arrow goes from higher priority to lower priority and that lowest-priority substituent is in the back. Figure
Related Theory A counterclockwise direction is an $S$ (sinister, Latin for left) configuration. A clockwise direction is an $R$ (rectus, Latin for right) configuration.

Hence, the correct answer is option: 'B'.
