Answer: C

Explanation:

To configure HSRP group 300 on a Cisco IOS router and ensure it becomes the active router when functional, the necessary commands are:

standby version 2: This command enables HSRP version 2, which supports an expanded group number range from 0 to 4095.

standby 300 priority 90: This sets the priority of the HSRP router to 90. Since the default priority is 100, a lower priority ensures this router will be the standby router if both routers are functional.

standby 300 preempt: This command allows the router to take over as the active router if it has a higher priority and the current active router fails.
