Answer: Pre-signed URL

The question asks which URL scheme allows unauthenticated access to files in Snowflake. Option C (Pre-signed URL) is correct because it provides temporary, time-limited access to files without requiring authentication into Snowflake or passing authorization tokens. This aligns with Snowflake's documentation where pre-signed URLs are specifically designed for granting temporary public access to staged files. The community discussion shows 100% consensus on option C, with comments confirming that this URL type allows access without authentication. Other options like File URL, Scoped URL, and Scoped File URL either don't exist as standard Snowflake URL types or require authentication mechanisms.
