Creating a new ID-dependent entity with a 1:N relationship is the best choice to represent an archetype/instance pattern in an E-R model. This is because an archetype represents a general category, while each instance represents a specific example falling within that category. Therefore, creating a new entity to represent the archetype and relating it to the instances with a 1:N relationship allows for multiple instances to be associated with a single archetype. The ID-dependency ensures that each instance is uniquely identified and linked to the archetype.
