The correct answer is B. Change the as1000 policy to orlonger. We must change the match type from longer to orlonger in the as1000 policy. The match type Orlonger matches if the prefix-length is equal to or greater than the route's prefix length, while the Longer match type only matches if the prefix-length is greater than the route's…

Explanation
We must change the match type from longer to orlonger in the as1000 policy. The match type Orlonger matches if the prefix-length is equal to or greater than the route's prefix length, while the Longer match type only matches if the prefix-length is greater than the route's prefix length.
