Packages that display orientation markings must:

Packages that display orientation markings are designed to indicate how they should be handled throughout the transportation process. The primary purpose of these markings is to ensure that the package remains in the correct position to avoid damage to the contents, which is especially critical for hazardous materials that may be sensitive to orientation.

The correct answer emphasizes the important requirement that these packages must stay in the correct position as indicated by the markings. This adherence helps in maintaining the safety of the material being transported, preventing leaks or other hazardous occurrences that could arise if the package is improperly handled or positioned during transit.

In contrast, the other options do not align with the purpose of orientation markings. Disposing of the package immediately or removing it from the shipping container undermines the effectiveness of the marking itself. Storing the packages upside down disregards the explicit instructions provided by the markings and could lead to potential safety risks. Therefore, maintaining the indicated orientation throughout transport is vital for safe and effective handling.
