Concept:The correct document is a bill of lading issued by the ship's captain.
Explanation:When goods are loaded on board a ship, the captain issues a bill of lading.
This document acknowledges receipt of the goods for sea transport.
It also serves as evidence of the contract of carriage.
A dock receipt is not given by the captain but by the dock authorities.
A mate's receipt comes into play inside the ship, but the captain issues the bill of lading.
A ship's manifest only lists cargo, not a receipt for the shipper.
Hence, the best answer is the bill of lading.
Answer:B. bill of lading
