To represent an association pattern in an E-R model, creating a new ID-dependent entity with a 1:N relationship to one of two parent entities is the best choice. This is because an association pattern signifies a relationship between two or more entities, where one entity is dependent on the other. Therefore, creating a new ID-dependent entity with a 1:N relationship to one of the parent entities allows for the representation of this relationship in the E-R model.
