Melissa's website provides users who access it via HTTPS with a Transport Layer Security $($TLS$)$ connection. Unfortunately, Melissa forgot to renew her certificate, and it is presenting users with an error. What happens to the HTTPS connection when a certificate expires?

Question $28$ options:

All traffic will be unencrypted.

Traffic for users who do not click OK at the certificate error will be unencrypted.

Trust will be reduced, but traffic will still be encrypted.

Users will be redirected to the certificate authority's site for a warning until the certificate is renewed.
