The correct answer is $false.

You supply $false to Set-SPOTenant -InformationBarriersSuspension because the parameter controls whether information barriers are suspended and a value of $false means they are not suspended so the information barriers remain active for SharePoint and OneDrive across the tenant.

$suspended is not the standard boolean literal that this cmdlet expects and it would only work if you had previously defined a variable with that name, so it is not the direct value to pass.

$true is incorrect because that value would suspend information barriers which disables them and that is the opposite of turning them on.

$enable is not a recognized boolean literal for this parameter and it is not the correct token to use with Set-SPOTenant -InformationBarriersSuspension.
