Correct Answer: B

If you’re a website owner and your website displays this error message, then there could be two reasons why the browser says the cert authority is invalid: 

• You’re using a self-signed SSL certificate.
• OR the certificate authority (CA) that issued your SSL certificate isn’t trusted by your web browser.
