Answer and explanation

Correct answer

C. Flux handles 0 to N items, while Mono handles 0 or 1 item.

Why

Flux is designed to handle streams of 0 to N items, allowing for potentially infinite streams, whereas Mono is used for scenarios where you expect 0 or 1 item, like a single result or completion signal.
