How should you ship the documents back?

Using the prepaid label provided with the documents is the best option because it ensures that the shipping costs are already covered, eliminating any out-of-pocket expenses for you. This method is generally more reliable, as the provided label is likely tailored for the specific shipping needs of the documents, such as insurance and tracking features. Additionally, using a prepaid label helps maintain a chain of custody for sensitive documents, which is crucial for legal and professional reasons. This method fosters accountability and traceability, ensuring that the documents arrive at their intended destination securely and on time.

The other possibilities offer less assurance in terms of tracking and cost management. Using any available shipping option could lead to unexpected costs or delays. Bringing the documents personally may not always be feasible, especially if distance or time constraints are involved. Shipping without a label can create complications, such as lacking a tracking mechanism or bearing the shipping costs yourself.
