Answer
Interfaces offer flexibility for multiple implementations.
Interfaces allow different parts of a system to interact through defined contracts without specifying how these contracts are implemented. This is particularly useful in scalable systems where different modules can have varied implementations. For instance, in an e-commerce project, you might have a PaymentProcessor interface that can have multiple implementations like CreditCardProcessor and PayPalProcessor.
