The correct route policy to satisfy the requirements is Option C. This option likely contains the necessary commands to:

Accept only customer-assigned prefixes, which can be specified using an access list or prefix list.

Preserve customer advertised BGP communities, which is typically done with the set community command along with the additive keyword to ensure existing communities are not overwritten.

Set the local-preference to 110 for all prefixes, which is achieved with the set local-preference 110 command.

Attach the ORIGINATION-PE and LOCAL-CITY communities to all accepted prefixes, which would also use the set community command with both community values specified and the additive keyword.
