You are working on an application that needs to print a report card for all students on campus. You will have various number of lists (all with the same order of information such as last name, first name, etc.). Your job is to write a program that reads in all of that information, and your goal is not to print duplicate report cards.

Which is the best choice for collecting this student information? And you don't care about order.

a. Read all student data in each file, and store them in a ArrayList

b. Read all student data in each file, and store them in a TreeSet

c. Read all student data in each file, and store them in an Array

d. Read all student data in each file, and store them in a HashSet

b. Use the add method from the parent class

c. Create a global ArrayList variable and use that variable to call the add method.

d. Create a class member variable that is ArrayList, and then use the add method from the parent class.
