Answer: C

Explanation:

✑ Vendors must be able to authenticate by using their Microsoft account when accessing Contoso resources.

You can invite guest users to the directory, to a group, or to an application. After you invite a user through any of these methods, the invited user’s account is added to Azure Active Directory (Azure AD), with a user type of Guest. The guest user must then redeem their invitation to access resources. An invitation of a user does not expire.

The invitation will include a link to create a Microsoft account. The user can then authenticate using their Microsoft account. In this question, the vendors already have Microsoft accounts so they can authenticate using them.
