C is correct: "You are limited a total of five onmicrosoft.com domains in your Microsoft 365 environment. Once they are added, they cannot be removed." https://learn.microsoft.com/en-us/microsoft-365/admin/setup/add-or-replace-your-onmicrosoftcom-domain?view=o365-worldwide

In Microsoft 365, the onmicrosoft.com domain is automatically created when you set up your subscription. However, Microsoft 365 subscriptions allow only one onmicrosoft.com domain per tenant.

1 + 5 additional - tested

Correct

In Microsoft documentation is specified max 5 onmicrosoft.com

The correct answer is C. 5. According to the first web search result1, you can add additional onmicrosoft.com domains to your Microsoft 365 subscription, but you are limited to a total of five onmicrosoft.com domains in your Microsoft 365 environment. Once they are added, they cannot be removed. You can use these domains as email addresses for your users, as well as for other services such as SharePoint and Teams.

Only 5 onmicrosoft domains are possible

Every Microsoft 365 tenant comes with one default onmicrosoft.com domain. However, you cannot add additional onmicrosoft.com domains to the subscription. The primary purpose of the onmicrosoft.com domain is to allow the tenant to be functional (for email, for example) even if there's no custom domain associated. So, the answer is: A. 1

5 domains https://learn.microsoft.com/en-us/microsoft-365/admin/setup/domains-faq?view=o365-worldwide#why-do-i-have-an--onmicrosoft-com--domain

I also don't understand the question, because it says to assign email addresses, that means that aliases count. I only hope that the question does not touch me, but if it does, I would put 5

The wording here could be misleading... while 5 is the maximum number of onmicrosoft.com domains that can be added, the questions states "The additional domains must be assignable as email addresses for users" which means we can only have one active... so depending on how you interpret the question it could go either way...
