Why each option
In Junos, lower route preference values are always more preferred, and by default, static routes have a higher preference (lower value) than RIP routes.
In Junos OS, the routing protocol process uses the route preference value (administrative distance) to determine the best path; a lower preference value always indicates a more preferred route.
While most default preference values are modifiable, certain route types, like direct routes, have fixed preferences, making the statement that "any" can be modified inaccurate.
By default, static routes have a preference value of 5, while RIP routes have a default preference of 100, meaning a static route is inherently more preferred than a RIP route.
A direct route (preference 0) is always preferred over a static route (preference 5) by default because it represents a locally connected network segment.
