Answer: Query history

The correct answer is B (Query history) because it provides detailed execution statistics of previously executed queries without requiring any additional compute credits or cost to the user. Query history stores metadata and performance metrics for all executed queries, allowing users to analyze execution plans, timing, and resource usage after the query has completed. Option A (Query Profile) is incorrect because while it provides detailed execution statistics, it requires re-executing the query to generate the profile, which consumes compute credits. Option C (Visualization chart) is unrelated to query execution statistics, and Option D (Query acceleration service) is a performance optimization feature that incurs additional costs when used.
