Answer: Scenario #6
Scenario #6 (C) is the most likely to experience an out-of-memory error due to data skew because it has the smallest executor memory (12.5 GB) among all configurations. When data skew occurs in a single partition, that partition must fit entirely within one executor's memory. With only 12.5 GB per executor, there's less headroom to handle oversized partitions caused by skew. While Scenario #1 (E) has only one executor, it has 100 GB of memory available, making it more resilient to skewed partitions. The community consensus strongly supports C with 89% agreement and the highest upvoted explanation, while E received only 2 upvotes and less convincing reasoning.
