Which status allows a change after proper authorization?

The chosen answer, "Allowable with mitigation," signifies a particular status that permits changes under certain conditions, namely after obtaining the proper authorization. This means that although there are specific restrictions or concerns associated with the change, it can still be permissible as long as appropriate measures or safeguards to mitigate risks are put in place and sufficient permissions are obtained from the relevant authorities.

This status acknowledges that while the change might entail some risk or be generally discouraged, it can be justified and approved through a careful assessment and subsequent approval process. The emphasis on "mitigation" highlights the importance of addressing any potential negative impacts associated with the change, making it a more acceptable option given the proper controls are established.

The options that imply a lack of permission or strict prohibitions, such as "Deemed allowable" or "Prohibited," do not encompass the necessary nuances involved in changing permissions when the proper channels are followed. "Allowable with exception" suggests that there are exceptions to rules but doesn't specifically emphasize the need for active risk management through mitigation. Therefore, the correct answer highlights a more proactive approach to managing changes, where authorization is critical.
