Which of the following kernel parameters instructs the kernel to suppress most boot messages?

There is no standard kernel parameter named `silent` for suppressing boot messages.

While some applications might use `verbose=0` for minimal output, it is not a standard kernel parameter for controlling boot messages.

There is no standard kernel parameter named `nomesg` for suppressing boot messages; `dmesg` is a command to view kernel messages, but `nomesg` is not a parameter.

The `quiet` kernel parameter instructs the kernel to suppress most messages printed to the console during the boot process. This is commonly used to provide a cleaner, less verbose boot experience for end-users.
