Final answer:
A variable declared as 'static int x' in a program results in only one instance for the entire program. This static variable is shared among all instances of the class and is not duplicated for each object or class declaration. Therefore , the correct answer options is b)
Step-by-step explanation:
When a variable is declared as 'static int x' in a program, it means that there will be c. Only one instance for an entire program. Static variables are class-level variables, which means that they are shared among all instances of the class. Instead of each object having its own copy of the variable, there is just one copy that is used by every instance of the class. This single instance is created when the class is loaded into memory and exists as long as the class stays loaded.
This is different from a typical instance variable which would have option b. One for each object that is instantiated. However, since we're discussing a static variable, the correct answer is that only one instance of this static variable is created for the entire program, not per object or per class declaration.
