Given the following class definition: public class Test private int score; private String student; private char grade; public boolean equals(Test t) { // missing code return true; else return false; } } Select the correct choice that supplies the missing code that allows the method to return true if both objects are equal, and return false otherwise: if (student == t.student && score == t.score && grade == t.grade) if (student.equals(t.student) && score == t.score && grade.equals(t.grade)) if (student.equals(t.student) && score == t.score && grade == t.grade) if (student == t.student && score.equals(t.store) && grade.equals(t.grade))
