A,B,C
Correct answer

In ETL systems like Ab Initio, data parallelism is achieved through Replicate (sending copies to parallel flows) and Partition components (splitting data by Range or Key). Gather is a coalescing operation that collects parallel streams back into one, reducing parallelism rather than enabling it.
