Which crime is defined as making a false statement while under oath?

• A. Perjury
• B. False Statement to Peace Officer
• C. Tampering with Evidence
• D. Fraud

Answer: (A)

Perjury is lying under oath. The key element is the oath or affirmation to tell the truth in a formal proceeding, such as in court or in sworn documents. Knowing your statement is false and still giving that false testimony makes it a crime. The other actions describe different offenses: lying to a peace officer is a separate false statement to an officer, not necessarily sworn; tampering with evidence involves altering or concealing evidence; fraud involves deceit for gain. So making a false statement while under oath specifically fits the definition of perjury.
