Q 1. Regarding class variables, what statement is accurate?

Ans: Class variables are also known as static member variables and it maintains a single shared value for all instances of the class. These variables are created when the program starts execution and destroyed automatically when execution ends. The default visibility these class variables are public, which means that the class members can be accessed from anywhere.so, A class variable is visible to all the instances of a class, does not vary from instance to instance is the correct option.
