Which type of authorization can be canceled without incurring expenses?

The correct answer is based on understanding that certain types of authorizations allow for cancellation without financial repercussions. When discussing the nature of travel authorizations, it is important to note that an authorization that has been signed can still be canceled if no expenses have been incurred related to that authorization. This means that while the authorization was approved, any potential costs associated with it were never realized.

In contrast, options discussing authorizations that were never signed or those limited to specific travel types miss the key element of expenses incurred. The emphasis is on the state of the authorization and the associated costs rather than the formalities of signing or the geographical scope. Therefore, if an authorization is signed but has not led to any financial transactions, it can indeed be canceled without financial implications. This understanding of the process helps clarify the governance of travel authorizations and their management within the context of travel policies.
