I think querying the rpd_tables table in performance_schema could also provide valuable insights.

I'm going with B) as well. It seems like the most straightforward way to check if the query was offloaded. No need to overcomplicate things.

Haha, I bet the HeatWave cluster is running so hot, it could melt an ice cube. But seriously, I think B) is the best option here.

I'm going with D) because the hw_data_scanned global status variable shows the amount of data scanned by the HeatWave cluster, which indicates if the query was offloaded.

I think B) is the correct answer. The rapid_query_offload_count global status variable tells you how many queries have been offloaded to the HeatWave cluster.
