The correct answer is D. quiet.
When a Linux system boots, the kernel displays messages that indicate the status of various hardware devices and software components. This information is useful for troubleshooting, but it can also be distracting or overwhelming for users who just want to log in and start using the system.
The kernel parameter "quiet" instructs the kernel to suppress most boot messages and only display essential information. This reduces the amount of output that appears on the screen during boot and can make the process faster and less distracting.
Option A, "silent," is not a valid kernel parameter. Option B, "verbose=0," is also not a valid kernel parameter and, in fact, would have the opposite effect of increasing the amount of output displayed during boot. Option C, "nomesg," is a valid kernel parameter but it instructs the kernel to not display kernel messages on the console, which is not the same as suppressing most boot messages.
