Explanation / Answer

Solution: -

classList[j].course = course;

                The statements are completely fine as here we are populating the course field of studentType structure variables present in the classList array.

classList.name.last = “ ” ; this statement is invalid as we classList is an array and not a studentType structure variable

course.credits = studentType.course.credits; this is invalid as we can make reference to a structure field by using the structure variable i.e. student here in this context and not studentType. So the correct one should be course.credits = student.course.credits;
