The correct answer is a written report signed by a person promising that the information they provided is true is called an affidavit. An affidavit is a legal document that contains a sworn statement made under oath, affirming the truthfulness of the information presented within it. This document is generally used in legal settings to confirm that the contents have been declared as fact, allowing it to be used as evidence in court.

The significance of the affidavit lies in its formal structure and the legal weight it carries. By signing an affidavit, the individual attests to the accuracy and truthfulness of their statements, making it a crucial tool in various legal, financial, and real estate transactions.

In contrast, a contract involves mutual agreements between parties but does not necessarily include sworn statements about the truth of the information. A disclosure typically refers to revealing certain information but lacks the formal vow of truth that an affidavit provides. A declaration, while it may also involve statements made, does not have the same legal binding effect under oath as an affidavit. Thus, the specificity of an affidavit as a sworn written statement makes it the correct choice in this context.
