Explanation

Two commands are needed: First, 'track 50 interface Fa0/1 ip routing' (E) creates tracking object 50 that monitors whether IP routing is operational on interface Fa0/1. Second, 'standby 10 track 50 decrement 20' (B) ties HSRP group 10 to that tracking object and decrements R1's HSRP priority by 20 when Fa0/1 goes down. If R1's priority drops below R2's priority, R2 takes over as HSRP active. Option A is invalid because it omits the decrement value. Option C tracks route reachability rather than interface state. Option D ('shutdown') is not valid HSRP tracking syntax - there is no shutdown action in HSRP object tracking.
