Answer and explanation
Correct answer
D. By allowing Subscribers to signal how much data they can handle.
Why
Backpressure in Reactive Streams allows Subscribers to control the data flow by signaling how much data they can handle at a time. This prevents the Publisher from overwhelming the Subscriber with too much data, thus ensuring a balanced data processing rate.
