Suppose a Student class has an indexed property. This property is used to set or retrieve values tofrom an array of 5 integers called scores[]. We want the property to report Invalid Index message if the user attempts to exceed the bounds of the array. Which of the following is the correct way to implement this property?

class Student { int[] scores = new int[5] {3, 2, 4, 1, 5}; public int this[ int index ] { get { if (index < 5) return scores[ index ]; else { Console.WriteLine("Invalid Index"); return 0; } } set { if (index < 5) scores[ index ] = value; else Console.WriteLine("Invalid Index"); } } }

class Student int[] scores = new int[5] 3 2 41 5; public int this[ int index ] set if (index < 5) scores[index] = value; else Console.WriteLine(Invalid Index);

class Student int[] scores = new int[5] 3 2 4 1 5; public int this[ int index ] get if (index < 5) return scores[ index ]; else Console.WriteLine(Invalid Index); return 0;

class Student int[] scores = new int[5] 3 2 4 1 5; public int this[ int index ] get if (index < 5) scores[ index ] = value; else Console.WriteLine(Invalid Index); set if (index < 5) return scores[ index ]; else Console.WriteLine(Invalid Index); return 0;
