B is the correct answer.
When configuring HSRP priority, follow these guidelines:
Assigning a priority allows you to select the active and standby routers. If preemption is enabled, the router with the highest priority becomes the active router. If priorities are equal, the current active router does not change.
The highest number (1 to 255) represents the highest priority (most likely to become the active router).

Definitely it is not D.
It sounds B but the word is not preemption, it is preempt.
The correct command is
Rt1(config-if)#standby 1 preempt
Done at the interface level.
