Answer: SQL warehouses

The question asks about the compute resource specifically for Databricks SQL. According to Databricks documentation and the community discussion consensus (100% agreement on B), SQL warehouses are the dedicated compute resource for Databricks SQL. Standard clusters (A) are used for Databricks Data Science & Engineering workloads, not SQL. Single-node clusters (B) are not the primary compute for Databricks SQL - SQL warehouses are optimized for SQL workloads with features like auto-scaling and query performance optimization. Downstream BI tools (D) are consumers of Databricks SQL, not the compute resource itself.
