Explanation
According to the question, the output displays that the interface is administratively down. Administratively down means that the interface is shut down. In order to up the interface, you will have to open the interface with the no shutdown command. Answer: A is incorrect. Had there been a physical problem with the interface, the output would not have displayed "administratively down". Instead, the output would be as follows: serial0 is down, line protocol is down Answer: B is incorrect. You cannot run this command on a router that is powered off. Answer: C is incorrect. Encapsulation has nothing to do with the output displayed in the question.
