A Correct answer
Explanation

The Singleton pattern ensures a class has only one instance and provides a global point of access to that instance. It involves a private constructor, a static variable to hold the single instance, and a static method that returns this instance (creating it if necessary). 'One Instance' and 'Static classes' are not recognized design patterns for this purpose.
