The command that changes the administrative distance of a route is structured to define a static route while also specifying the administrative distance using the "AD NUMBER" at the end of the command. This is crucial because administrative distance is a value used by a router to rank routes, with lower values being preferred over higher ones when there are multiple routes to the same destination from different sources.

In this command, the format clearly indicates that you are defining a static route to a specific destination IP network and subnet mask, alongside the next-hop IP address. By appending the administrative distance, the route's precedence can be adjusted, allowing for more control over routing decisions.

The other options either do not follow the correct syntax for changing administrative distance or refer to commands that aren't recognized in common routing protocols. In particular, the other commands suggested use terms and structures that do not align with the standard routing command configurations in Cisco networking. Thus, the correct answer stands out as it accurately reflects how to set up a static route with a customized administrative distance.
