Draw a use case diagram (specify the relationship if any) for a university registration system. Class registration, which is the basic flow (course number, section number, term, year) is carried out by the registration clerk. He also checks whether the student has opted for registration of special classes (alternative flow). If yes, the Registration for special classes use cases will be performed. Registering for a special class requires prior permission of the instructor in addition to the other steps carried out for a regular registration. In normal cases, only class registration would be performed, because students would have met the prerequisite requirements. However, in situations where a student has not taken one or more of the prerequisites, the Prereq course not completed use case is performed. Student billing is initiated by the University office, which interacts with the student by mailing the tuition invoices. Read the Requirement Specifications thoroughly and answer the following questions: A. Identify different actors and use cases of the system from a given problem statement

B. Identify different types of relationships if any such as (include, extend, generalization) between the use cases.

C. Draw a use-case diagram.
