When an employer is unable to obtain a certificate of age or a work permit for a minor employee, relying on any of the documents mentioned in options a, b, c, or d would not be considered appropriate or reliable evidence of age. Each of these documents can be easily fabricated or manipulated and may not accurately reflect the minor's true age. In such cases, it is essential for the employer to follow the applicable laws and regulations regarding the employment of minors, which typically require proper documentation to ensure compliance. It is recommended that the employer consults with local labor authorities or legal professionals to determine the appropriate course of action in this situation.
