Answer:
C06
Step-by-step explanation:
From the attached table or images of Solmaris Condominium Group database we can see that the "ServiceRequest" table has 'ServiceID 6' attached to 'CondoID 14'.
However, in the "CondoUnit" table, we have the 'CondoID 14' attached to 'UnitNum C06.'
Hence, In the Solmaris Condominium Group database, the number of the condo unit needing service with service_id 6 is "C06"
