Why each option
To successfully remove a static route from the Junos OS configuration, the `delete` command must precisely specify the route's destination prefix within the `routing-options static route` hierarchy.
The command attempts to delete the entire route by also specifying an attribute of the route (`qualified-next-hop`), which is unnecessary and incorrect syntax for deleting the route itself.
The command `delete routing-options static route 166.74.67.131/32 qualified-next-hop` would attempt to delete only the `qualified-next-hop` attribute from the specified route, not the route entirely.
The `delete routing-options static route 166.74.67.131/32` command is the correct and most straightforward way to remove a specific static route in Junos OS by targeting its destination prefix.
This option is identical to A; specifying an attribute like `qualified-next-hop` when deleting the entire route by its prefix is incorrect syntax for full route removal.
