C Correct answer
Explanation

Gather is a de-partitioning component because it collects data from multiple partitioned flows and reunites them into a single flow. The opposite operation is partitioning (by key, round robin, etc.). Components like Partition by key and Join are partitioning operations, not de-partitioning.
