Refer to the exhibit. An IP SLA is set up to use the backup default route when the primary route is down, but it is not operating as intended. Which command resolves the issue?

A R1(config)# ip route 0.0.0.0 0.0.0.0 2.2.2.2 10 track 1
B R1(config}# ip route 0.0.0.0 0.0.0.0 2.2.2.2
C R1(config)# ip sla track 1
D R1(config)# ip route 0.0.0.0 0.0.0.0 1.1.1.1 track 1

Explanation

A tracked static route is installed only while its associated track object is up. Adding track 1 to the primary default route (1.1.1.1) binds that route to the SLA monitor. When the IP SLA reachability test fails, track 1 goes down, removing the primary route and allowing the backup default route through 2.2.2.2 (AD 10) to become active.
