What should a consultant recommend to meet these criteria?

A customer is starting a new children’s fashion brand and wants to use a dedicated business unit within their existing Enterprise 2.0 account. They anticipate many of their current Enterprise contacts will subscribe to the children’s brand, however, they want to separate subscriber opt-outs of the Enterprise and children’s brands. The customer has minimal technical resources available for implementation and support.

What should a consultant recommend to meet these criteria?
A . Select "Use separate ‘Subscription Center’ for this business unit" in Settings
B. Create attributes for each child business unit in "Profile Management" to record unsubscribes
C. Create a Business Unit Filter in ‘All Subscribers’ List to record unsubscribes
D. Select "Subscribers will be unsubscribed from this business unity only" in Settings

Answer: D

Explanation:

To separate subscriber opt-outs of the Enterprise and children’s brands, Northern Trail Outfitters should select “Subscribers will be unsubscribed from this business unity only” in Settings for each child business unit. This will allow subscribers to unsubscribe from one brand without affecting their subscription status for another brand.
