The correct answer is A) a Bill of Lading. A cargo exception would appear on a Bill of Lading, which is a document that details the type, quantity, and condition of the cargo being transported. If there are any discrepancies or exceptions with the cargo, such as damage or missing items, these would be noted on the Bill of Lading. The other answer choices are incorrect because they do not directly relate to documenting cargo exceptions. A Letter of Indemnity is used to provide a guarantee, a cargo manifest is a list of all the cargo being transported, and an Export Declaration is a document filed with customs when exporting goods.
