B.
When the update addresses security issues.

When the security update involves areas of the OS that are actively being used by network operations.

D.
None of the above.

Explanation:
Just because a newly released NOS update addresses security issues, it does not mean that it is relevant to your environment and the way in which you use the OS. You should apply the update if you have determined that the current use of the NOS requires the update to be performed, or if the security update involves areas of the OS that are actively being used by network operations.
