To represent a multivalued attribute in an E-R model, we create a new entity with a 1:N relationship, which is ID-dependent. This allows us to store multiple values for the attribute in separate tuples. In this case, each tuple in the new entity represents a unique value for the multivalued attribute. Hence, option A is the correct choice.
