I thought it might change with input size, but I guess not.

I think option C is correct - the timing of when a change in a configuration parameter is reflected can vary depending on the parameter. And option E also looks right, as those are all valid boolean values that can be used.

Based on my understanding, NIST SP 800-53A seems like the most relevant publication for this type of question. I'll mark that as my answer.
