Solution

The valid way to access a static variable within a static method is by using the class name followed by the variable name. So, the correct answer is b. className.variableName.

Here's why:

a. this.variableName: 'this' keyword refers to the current instance of the object and cannot be used to access static variables.

b. className.variableName: This is the correct way to access a static variable. 'className' refers to the class that the static variable is declared in.

c. variableName: This can sometimes work if you're accessing the static variable from within the same class, but it's not a good practice. It's better to always use the class name for clarity.

d. super.variableName: 'super' keyword is used to refer to the immediate parent class instance variable, it cannot be used to access static variables.
