The correct answer is B) the net weight of each hazardous cargo. The dangerous cargo manifest is required to include information such as the UN identification numbers, the stowage location of hazardous materials, and a description of the packaging. However, it does not require the manifest to indicate the net weight of each hazardous cargo item. The net weight is not a mandatory piece of information on the dangerous cargo manifest. The other answer choices are incorrect because A), C), and D) are all required to be included on the dangerous cargo manifest, per the relevant regulations.
