You have a Microsoft Entra tenant named contoso.com.
You plan to collaborate with a partner organization that has a Microsoft Entra tenant named fabrikam.com.
Fabrikam.com uses the following identity providers:
• Google Cloud Platform (GCP)
• Microsoft accounts
• Microsoft Entra ID
You need to configure the Cross-tenant access settings for B2B collaboration.
Which identity providers support cross-tenant access?
For configuring Cross-tenant access settings for B2B collaboration, the supported identity providers include Google Cloud Platform (GCP), Microsoft accounts, and Microsoft Entra ID. This means users from these identity providers can be added for collaboration across tenants in Microsoft Entra. Therefore, all listed providers (GCP, Microsoft accounts, and Microsoft Entra ID) support cross-tenant access settings for B2B collaboration.
I would go for D Link: https://learn.microsoft.com/en-us/entra/external-id/identity-providers
another not clear question: if the question is "You need to configure the Cross-tenant "access settings*" I will go for A, only Entra ID tenant supports cross-tenant access settings (like trust settings). If the question is "You need to configure the Cross-tenant access" I will go for D: I can create B2B configuration for all the listed providers

D. GCP (Google Cloud Platform, referred to as Google federation), Microsoft accounts, and Microsoft Entra ID. - The identity providers that support cross-tenant access settings for B2B collaboration in Microsoft Entra include Microsoft Entra ID, Microsoft accounts, and Google federation. This means you can configure cross-tenant access to allow guest users to authenticate using their Microsoft Entra accounts, personal Microsoft accounts, or their Google accounts.
I go with C) GCP accounts are associated with Google Cloud services. they are not directly used for Microsoft Entra cross-tenant collaboration. Within a single tenant it is possible to invite a GCP user but it is not possible to be used for cross tenant scenarios
In addition: I checked the settings in entra admin center for external identities --> Cross tenant settings. With the organizational settings of the cross-tenant access settings it says: "Use cross-tenant access settings to manage collaboration with external Microsoft Entra tenants. For non-Microsoft Entra tenants, use collaboration settings." In the external collaboration settings you can invite guest users to your tenant. And yes, there you can add GCP users
for the same reason you can't add Microsoft Accounts. Whan you add an org in cross-tenant access settings you see "Add an external Microsoft Entra tenant by typing one of its domain names or tenant ID if from another Microsoft cloud."
