What should you do to resolve this problem?

Your company has a Microsoft Exchange Server 2019 organization. All email sent to the company uses an SMTP domain named contoso.com. You create a Microsoft 365 E5 subscription that has a default domain named contoso.onmicrosoft.com.

You run the Microsoft Office 365 Hybrid Configuration wizard, and receive the following error message:

"No shared domains have been detected within the Exchange Online and on-premises organizations. Make sure that your primary domain (such as contoso.com) is added to both Exchange Online and on-premises."

You are unable to advance to the next step in the wizard.

What should you do to resolve this problem?
A . From a public registrar, register a new domain name and then add the domain name from the Microsoft 365 admin center.
B . From Active Directory, add contoso.onmicrosoft.com to the UPN suffix list.
C . From the Exchange admin center in Exchange Online, modify the contoso.onmicrosoft.com accepted domain.
D . From the Microsoft 365 admin center, add contoso.com as a domain.
