Answer:
The judge is correct.
Explanation:
Burden of proof is a tool and a term used in law used to define who is the person responsible for supporting a statement or concept. The term specifies that the person responsible for a particular claim is also the one who must offer the evidence necessary to support it.
Karin, who is claiming she is innocent of the crime she committed because she was acting under duress, but she has not provided any proof of it, so the judge of the case acted correctly in asking burden of proof to Karin, so she could prove her innocence.
