Consider the following example.
Example:
University name BITS has maintained the two relations to store the information about the faculty table and Teaches table. The faculty table stores the faculty_id (faculty_id has the unique id of faculty in the whole university) and faculty_name. The Teaches table stores the Course_id, Course_Name, and faculty_id. So the university admin department prints the faculty_name and Course_Name.
Consider DEGREE(faculty) is D1, DEGREE(Teaches) is D2.
Which of the following option is true for D1+D2?
1
2
2
3
3
