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

Here's why:

a. className.variableName: This is the correct way to access a static variable. Static variables belong to the class, not the object. Therefore, they should be accessed by using the class name.

b. super.variableName: This is incorrect. The 'super' keyword is used to access/call the parent class members (variables/methods).

c. this.variableName: This is incorrect. The 'this' keyword is used to call the current class members (variables/methods). 'this' cannot be used to access static fields.

d. variableName: This can sometimes be correct if you're accessing the static variable within the same class, but it's not a good practice. It's better to access static variables using the class name for clarity and avoiding ambiguity.
