B. Unset the Preserve Partitioning flag on the output of each parallel dataset.
C. Explicitly specify hash partitioning and sorting on each input to the Join stage.
D. Add a parallel sort stage before each Join input, specifying the "Don't Sort, Previously Grouped" sort key mode for each key.
E. Set the environment variable $APT_SORT_INSERTION_CHECK_ONLY.

Question 2
