Explanation

Databricks SQL defaults to ANSI SQL as its SQL dialect, making C correct - this was a deliberate shift introduced to improve cross-platform compatibility and standards compliance. Spark SQL (B) is the dialect Databricks historically used and is still available, but it is no longer the default; Databricks moved away from it precisely because Spark SQL has non-standard behaviors that could surprise users coming from other databases. Databricks SQL (A) and Delta SQL (D) are not real SQL standards - they are distractors designed to sound plausible given the platform name. Memory tip: think "ANSI = standard" - Databricks adopted ANSI to become more standard and enterprise-friendly, just like how most major databases (PostgreSQL, SQL Server) advertise ANSI compliance.
