Answer: SnowSQL, Snowflake connector for Python

Key pair authentication in Snowflake is supported by SnowSQL (D) and the Snowflake connector for Python (E). SnowSQL, the command-line client, allows key pair authentication as documented in Snowflake's official documentation. Similarly, the Snowflake connector for Python supports this authentication method for programmatic access. Snowflake Marketplace (A) is for data sharing and does not involve authentication in this context. SnowCD (B) is a network diagnostic tool that does not use key pair authentication. Snowsight (C) is the web-based UI that primarily uses username/password or SSO, not key pair authentication. The community discussion confirms this with 100% consensus on DE and references the official documentation.
