Explanation

Option B is correct because all three components are properly configured: the ACL correctly matches the source network (10.1.1.0 0.0.0.255 as the source, any as destination), the route-map references the ACL by its correct name (acl-to-red), and the VRF import statement uses the proper syntax import ipv4 unicast map rm-to-red - where map is the required keyword preceding the route-map name.

Option A is wrong on two counts: the ACL has the source and destination reversed (any source, specific destination), and the route-map matches on access-list number 50 instead of the named ACL acl-to-red.

Option C is wrong because the VRF import statement uses route-map acl-to-red - referencing the ACL name where the route-map name should be, and the keyword should be map, not route-map.

Option D is wrong because the map keyword is missing entirely from the import statement; import ipv4 unicast acl-to-red is not valid syntax - you cannot reference a policy object directly without the map keyword.

Memory tip: Think "Source first, MAP to import" - the ACL always lists the source network first (not destination), and the VRF import command always uses the keyword map before the route-map name, not route-map.
