New certificate option can be used if we have to change a CA, for this a new CSR would be required. With the existing Renew request will work

Correct answer is C. You cannot renew an expired certificate, in the following article says "All valid certificates have a Renew link in the details pane...", if a certificate has expired, is not valid. https://learn.microsoft.com/en-us/exchange/architecture/client-access/renew-certificates?view=exchserver-2019#use-the-eac-to-create-a-certificate-renewal-request-for-a-certification-authority

Given answer seems to be correct. https://docs.microsoft.com/en-us/exchange/architecture/client-access/renew-certificates?view=exchserver-2019 To renew a certificate that was issued by a CA, you create a certificate renewal request, and then you send the request to the CA. The CA then sends you the actual certificate file that you need to install on the Exchange server.
