True is correct.

The True option is correct because Information Barrier policies in Microsoft 365 and Teams can be targeted to users that exist in the HarborTech tenant and that includes guest users who are added as Azure AD B2B guest accounts. These policies are created and managed in the Microsoft Purview compliance center and they apply to segments of directory users so guest accounts can be included when you define the segments and rules.

To include guest accounts you must have the guests provisioned in your Azure Active Directory and then include them in the groups or attribute-based segments that the Information Barrier policies use. When the prerequisites and licensing requirements are met the policies will propagate to supported workloads including Microsoft Teams.

The False option is incorrect because it asserts that HarborTech cannot apply Information Barrier policies to guest accounts. That blanket statement is wrong when guests exist as directory users and are explicitly included in the policy segments or groups.
