A$)$ You are tasked with implementing a configuration manager for a desktop application. The application should load configuration data $($like user preferences, system settings$)$ once and share the same configuration object throughout the entire application lifecycle. Use the Singleton pattern to implement this scenario. Task: Draw a UML diagram showing how to apply the Singleton design pattern to ensure only one ConfigurationManager instance is created and accessed globally.

B$)$ Imagine you are designing an online payment system where you need to support different types of payment methods $($e$.$g$.,$ CreditCard, PayPal, and ApplePay$).$ Each payment method implements a Payment interface, and you want to ensure the correct payment method object is created based on user selection. Use the Factory design pattern to solve this. Task: Draw a UML diagram that shows how to implement the Factory pattern for the PaymentFactory class, which is responsible for creating instances of different payment methods.
