When you ask Siri or Cortana a question, how will you know if the operating system is working?

Question $15$ options:

Since Siri and Cortana work off of read$-$only memory, when they give you an answer, you know the operating system is working.

Since the operating system is what you interact with to get help, by asking them a question, when the answer is supplied, you know the operating system is working.

Siri and Cortana use the web not the operating system, so you do not need to know if the operating system is working.

Siri and Cortana are part of the boot process not the operating system process, so you will not know if the operating system is working.
