Final answer:
The Annual transit coverage is the best option for coverage of all incoming and outgoing shipments, as it offers blanket coverage for all shipments over the course of a year.
Step-by-step explanation:
The coverage form that would provide coverage for all incoming and outgoing shipments is the Annual transit coverage. This type of insurance policy is designed for businesses that frequently ship goods, covering all shipments, both inbound and outbound, over the course of a year. It's a blanket coverage that typically does not require the insured to report individual shipments, streamlining the process and ensuring that all goods in transit are covered.
Trip transit coverage, on the other hand, is more suited for single or infrequent shipments, providing coverage for goods on specific trips. Meanwhile, Mail coverage is tailored to items sent via courier or postal services and would not be comprehensive for all type of shipments.
