What is a key advantage of using asynchronous methods in a Spring Boot REST API?

AIt guarantees that all tasks run on the main thread sequentially

BIt allows the server to handle other requests while waiting for long tasks to complete

CIt disables multi-threading to avoid concurrency issues

DIt forces the client to wait until the server finishes processing
