Selected Answer: C
The correct answer is: C. It allows you to debug multiple modules at the same time - "fw ctl debug" is a more advanced and flexible tool for kernel debugging. It allows you to enable debug flags for multiple kernel modules simultaneously, control the buffer size, output to files, and more. - "fw ctl zdebug" is a shorthand command that quickly sets kernel debug flags (mainly for the "fw" module) and outputs to the console with a default buffer of 1MB. It is mainly used for quick, on-the-fly troubleshooting and is less flexible.
