What is the difference between coding and programming?

Can't be M-D because question specifically states "Each Warehouse record has a distinct record owner". By the way, does anyone else wonder if John is an actual person? :)

When we define relationship in salesforce through custom fields there is no One-to-Many or Parent-Child relationship. It can be either Lookup or Master-Detail relationship. Also, in salesforce Child record of a Master-Detail relationship can't have owner. Here Warehouse is child to Account. As the question says warehouse has distintct owner, the answer should be Lookup. Please fixt the answer.
