I think B is the answer as per this text (https://help.salesforce.com/s/articleView?id=data.c360_a_reconciliation_rules.htm&type=5) -
Note Reconciliation rules don’t apply to contact points such as email or phone number. All contact points remain part of a unified profile, so all contact points are available when creating activations for segments on unified profile. Use the source priority order in activations to make sure you deliver a contact point from the desired source to your activation target.
