I would like to ask this question from Inbuilt Classes topic in division Inbuilt Classes of Object Oriented Programming

Answer 1

Right option is (c) Each class has an associated Array class

The best I can explain: The Array class is associated with all the other classes. This gives us the flexibility to declare an array of any type. The index goes from 0 to n, where n is some fixed size for array.
