AC, because the routes in the routing table are /28, hence it should be /25 or longer not /25 exact. Hence A is valid. All the routes in the routing table are BGP learnt routes, so no need to remove the BGP command from the export policy, as it will not make a difference. Since we want to summarise routes into a /25, we have to use the aggregate route, hence D is a valid answer.
