Which command will allow Router B to always become the active router for HSRP?

The command standby 1 priority 150 will set the HSRP group of 1 on this router to a priority of 150. As long as all other routers are set to the default of 100, this router will become the default router on the next election. The commands standby 1 priority 70, hsrp 1 priority 150, and hsrp 1 priority 90 are incorrect.
