Multiple choiceMediumchapter-19-curatedpremiumproject-reactorproject-reactor-mono
Answer and explanation
Correct answer
A. Return a Mono<User> without blocking the current thread.
Why
To maintain non-blocking behavior, you should return a Mono<User> immediately. The actual database call should be handled asynchronously, often using non-blocking database clients.
