Since setSide is a function of the Square class and box is an object of the Square class, we need to call the function on the box object using the dot notation. Therefore, the correct statement is box.setSide(5). Option A is incorrect because setSide needs to be called on the box object. Option C is incorrect because setSide is not a static function, so it cannot be called on the class itself. Option D is incorrect because we need to pass a value to the setSide function, so it cannot be assigned directly to 5.
