Solution
The correct answer is: Private constructor ensures only one instance of a class exist at any point of time.
Here's why: A private constructor in a class means the class cannot be instantiated from outside the class. This is often used in the Singleton Design Pattern, which ensures that only one instance of the class exists in the Java Virtual Machine (JVM) at any time. This is done by providing a global access point to the single instance such as a static method that returns the instance. The constructor is made private to prevent creating additional instances from outside the class.
