Solution

The answer is a. The instance variable shadows the static variable.

Here's a step-by-step explanation:

  1. In Java, when an instance variable is declared with the same name as a static variable in a class, the instance variable shadows the static variable. This is known as variable shadowing.

  2. Variable shadowing occurs when a variable declared within a certain scope has the same name as a variable declared in an outer scope.

  3. When the shadowed variable (in this case, the static variable) is referenced within the scope of the shadowing variable (the instance variable), the shadowing variable is used instead.

  4. However, it's still possible to access the shadowed static variable by using the class name. For example, if the class name is 'MyClass' and the static variable is 'myVar', you can access the static variable with 'MyClass.myVar', even if there's an instance variable with the same name.

  5. This does not cause a compilation error, and both variables are accessible, but care must be taken to avoid confusion.
