This question is testing B2B collaboration, not B2B direct connect. A guest invitation creates or uses a B2B collaboration guest relationship. Microsoft states that cross-tenant access settings determine both inbound access by external users to your resources and outbound access by your users to external organizations.
Inbound access controls whether users from an external Microsoft Entra organization can access resources in your tenant, while outbound access controls whether your users can access resources in an external organization. Microsoft also states that default cross-tenant access settings apply to all external organizations unless organization-specific settings exist.
For fabrikam.com, organization-specific settings override the default settings. Because Inbound B2B collaboration is All blocked, a Contoso user cannot invite a Fabrikam user as a guest into Contoso. Therefore, the first statement is No. For adatum.com, no organization-specific blocking rule is shown, so the default tenant setting applies; B2B collaboration is enabled by default for external Microsoft Entra organizations, so the second statement is Yes.
For the third statement, a Contoso user accepting an invitation from Fabrikam means the Contoso user is accessing Fabrikam as an external guest, which uses Outbound B2B collaboration from Contoso to Fabrikam.
Since outbound B2B collaboration for fabrikam.com is All blocked, the answer is No.
