I have a service composition with three services. Service A retrieves a list of country codes from a database and keeps this data in memory while interacting with Service B and Service C. However, because Service A is concurrently invoked many times, and because each instance of Service A loads its own copy of the country code data into memory, the demands on the overall infrastructure become too high and performance and reliability are negatively affected. Which service-orientation principle can be applied to help solve this problem? Select the correct answer.
A) Service Reusability
B) Service Autonomy
C) Service Abstraction
D) Service Statelessness

Service Statelessness can help solve the problem by ensuring that Service A does not maintain state information in memory across multiple invocations, reducing memory usage and improving performance.
