A Correct answer
Explanation

Broadcast increases data parallelism by sending each input record to all output partitions. This maximizes parallel processing because the same data is available to multiple downstream operations simultaneously. The other options are incorrect - Broadcast definitely increases parallelism rather than decreasing it or being unrelated.
