Which of the following reflects an individual’s legally sworn assertion under oath?

An affidavit is a written statement made under oath, which serves as a declaration that the information contained within it is true to the best of the individual's knowledge. It is commonly used in legal proceedings and can be utilized to support various claims, providing a sworn testimony that holds legal weight.

This legally sworn assertion is important in many contexts, such as court cases, where the truthfulness of statements must be verified. The individual signing the affidavit is typically required to do so in the presence of a notary public or another authorized individual, ensuring that the affidavit is executed properly and under lawful conditions.

In contrast, a warrant is an order issued by a judge or magistrate for the arrest of an individual or the search of property, a contract is a legally binding agreement between two or more parties, and a power of attorney is a legal document that allows one person to act on behalf of another. While each of these documents serves important legal functions, they do not represent sworn assertions made under oath like an affidavit does.
