The ACL rules are evaluated in order of their sequence numbers. Rule 10 denies packets from the source network 20.1.1.0/24, and since it is listed before rule 20, which permits the same network, packets from network 20.1.1.0/24 will be denied as soon as rule 10 is matched. Therefore, the correct statement is that packets from network 20.1.1.0/24 network will be denied.
