What is the portion marking for confidential information from a Special Access Program (SAP) with the code word abbreviation HT?

The appropriate portion marking for confidential information associated with a Special Access Program (SAP) that has a code word abbreviation of HT is crafted to reflect both the level of classification and the specific program affiliation.

In this case, the correct notation should prioritize the Special Access Program label over the confidentiality level in accordance with established guidelines. Therefore, using "NOT C" signifies that the information is not classified as Confidential by itself, while “HT” designates the specific SAP designation to which the information belongs. This approach ensures clarity and compliance with marking protocols, allowing for immediate recognition of the information’s sensitivity and its source.

The other marking options fail to represent the proper hierarchy or could be misleading regarding the document's classification status, emphasizing why understanding the correct format is essential for proper information handling within sensitive contexts.
