Which of the following services provides insurance coverage up to a certain limit?

Registered Mail provides insurance coverage up to a certain limit, making it ideal for sending valuable items securely. This service offers a higher level of security than standard mail because it is tracked at every step of its journey and requires a signature upon delivery. The insurance coverage ensures that, in the event of loss or damage, the sender can be reimbursed, which is a significant advantage when shipping important documents or high-value items. This level of service and security is not typically provided by the other mailing options, which either do not offer insurance or have limited tracking and security features.
