Selected Answer: AC
The correct answers are: A. uptime - This command directly shows how long the system has been running, along with other information like load average and number of users. C. top - While primarily used to monitor processes and resource usage, the top command also displays system uptime in its header. The other options are incorrect: B. up: There is no standard Linux command called up. D. uname -u: This command shows the system's kernel version. E. time –up: The time command is used to measure the execution time of other commands. There is no -up option for it.
