What is perjury?

• A. The offense of lying in court after taking an oath.
• B. Providing an alibi without evidence.
• C. A false statement to a detective during an interview.
• D. Withholding information during an investigation.

Answer: (A)

Perjury means lying under oath in a court or other sworn proceeding. The key is the oath to tell the truth; making a false statement while that oath is in effect is what makes it perjury. This is why it’s the best description: the crime hinges on knowingly giving false information after swearing to be truthful. Lying about an alibi without evidence, or giving a false statement to a detective, aren’t perjury unless they occur under oath. Withholding information during an investigation isn’t perjury either—it’s typically treated as obstruction or concealment, a different offense.
