  Both Path-1 and Path-2 are down. If Path-2 becomes available again, how does the headend router select the secondary LSP path?

  A. The router will switch to Path-2 because it is the first secondary path configured in the list.
  B. The router will not switch to Path-2 because the current path has the longest uptime.
  C. The router will switch to Path-2 because it is a more preferred path.
  D. The router will not switch to Path-2 because the router will not revert to another secondary path.
  C. The router will switch to Path-2 because it is a more preferred path.
