Answer and explanation

Correct answer

A. Tracing the flow of reactive streams across asynchronous boundaries.

Why

WebFlux involves asynchronous execution, making it challenging to trace the flow across different reactive stream operations, as each transformation might occur on different threads, complicating debugging compared to the more linear flow in Virtual Threads.
