Affidavit is defined as:

• A. A written declaration made before an authorized officer that the person executed the instrument freely.
• B. Is a signed written statement that is sworn to be true to the best knowledge of the person signing it.
• C. To postpone a case to a future date, a continuance.
• D. An appellant asks a higher court to review the transcript of the proceedings.

Answer: (B)

An affidavit is a written statement of facts that a person signs and swears to be true under oath. The important elements are that it is in writing, it is signed by the person making the statement, and the person swears that its contents are true to the best of their knowledge. This matches the given definition: a signed written statement that is sworn to be true to the best knowledge of the person signing it. Affidavits are commonly used to present factual assertions to a court or in support of motions, with the oath lending credibility and accountability. The other descriptions refer to an acknowledgment of execution, a postponement of a case (continuance), or an appeal to a higher court, which are different concepts and not what an affidavit is.
