What is the appropriate approach to do this?
A . Use the requirement element and relationship defined in the UML specification.
B . Create a profile that stereotypes Class as requirement and Dependency as the relationship.
C . Create a new MOF metamodel that includes UML and adds the desired requirement element and relationship.
D . Assign tag values that ascribe the desired requirement type to a UML Requirement and Dependency relationship.

Answer: B

Explanation:

UML allows the introduction of new concepts that are not part of the standard UML metamodel by creating a profile. To add capabilities for modeling requirements and tracing relationships in UML, a profile can be created where a Class is stereotyped to represent a requirement, and a Dependency is stereotyped to represent the trace relationship. This approach is both practical and conforms to the UML standard’s mechanisms for extending the language. It is a common practice to create such profiles for requirements engineering within the UML framework. This conforms to the UML 2 Superstructure Specification, which provides guidelines on creating and applying profiles and stereotypes.
