A. dmesg -t
B. dmesg -W
C. dmesg -x

The defaultdmesgoutput shows the timestamps in a raw format (seconds since the kernel started), while the-Toption translates these timestamps into a human-readable date and time.
* Option A (Incorrect):The-toption is used to remove the timestamps entirely from the output.
* Option B (Incorrect):The-xoption provides extended information about the message (e.g., facility, level).
* Option D (Incorrect):The-Woption waits for new messages and does not convert timestamps to a human-readable format.
