In a CNC milling operation, the tool has to machine the circular arc from point $(20, 20)$ to $(10, 10)$ at sequence number $5$ of the CNC part program. If the center of the arc is at $(20, 10)$ and the machine has incremental mode of defining position coordinates, the correct tool path command is

• A. N $05$ G$90$ G$01$ X−$10$ Y−$10$ R$10$
• B. N $05$ G$91$ G$03$ X−$10$ Y−$10$ R$10$
• C. N $05$ G$90$ G$03$ X$20$ Y$20$ R$10$
• D. N $05$ G$91$ G$02$ X$20$ Y$20$ R$10$
