You have a class Student:public class Student{ public int studentId; public String studentName; public String studentGrade; public Student() { } public Student(int studentId, String studentName, String studentGrade){ this.studentId = studentId; this.studentName = studentName; this.studentGrade = studentGrade; }}You have a child class CollegeStudent:public class CollegeStudent extends Student {}Then you execute the following snippet of code:CollegeStudent myCollegeStudent = new CollegeStudent(1, "Alice", "3rd");What is the error in this snippet of code?Instruction: Choose the option that best answers the question. Answer ChoicesYou cannot specify multiple constructors for the parent class, though this is allowed in child classesYou cannot use the parameterized constructor in the base class to instantiate the CollegeStudent derived classYou need to have additional constructors in the base class to support the instantiation of the CollegeStudent derived classYou have to use the “object” keyword to create an object of a derived class
