A. B. C. D.B
Every Azure AD directory comes with an initial domain name in the form of domainname.onmicrosoft.com. The initial domain name cannot be changed or deleted, but you can add your corporate domain name to Azure AD as well. For example, your organization probably has other domain names used to do business and users who sign in using your corporate domain name. Adding custom domain names to Azure AD allows you to assign user names in the directory that are familiar to your users, such as "alice@contoso.com.' instead of 'alice@domain name.onmicrosoft.com'.
Scenario:
Network Infrastructure: Each office has a local data center that contains all the servers for that office. Each office has a dedicated connection to the Internet.
Humongous Insurance has a single-domain Active Directory forest named humongousinsurance.com
Planned Azure AD Infrastructure: The on-premises Active Directory domain will be synchronized to Azure AD.
https://docs.microsoft.com/en-us/azure/active-directory/fundamentals/add-custom-domainTo support the planned infrastructure, you need to define a custom domain name for Azure AD. This domain name should match the domain name used by your organization's Active Directory domain, which in this case is "humongousinsurance.com". This will ensure that when you synchronize your on-premises Active Directory domain with Azure AD, user accounts will have the correct domain suffix.
Option A ("humongousinsurance.onmicrosoft.com") is the default initial domain name provided by Azure AD, and is not recommended for production use. This domain name is intended for temporary use during initial setup and testing.
Option C ("ad.humongousinsurance.com") is a subdomain of the existing Active Directory domain, and is not necessary for the purposes of defining a custom domain name for Azure AD.
Option D ("humongousinsurance.local") is not a valid domain name for use with Azure AD, as the ".local" top-level domain is reserved for use with private networks and is not routable on the public internet.
Therefore, the correct answer is B ("humongousinsurance.com").
