Answer: Duo Mobile

The correct answer is B (Duo Mobile) because Snowflake's default MFA service specifically integrates with Duo Mobile for authentication. The community discussion shows 100% consensus on answer B, with multiple users confirming this and providing official Snowflake documentation links that specify Duo Mobile as the required application. While one comment suggested Microsoft Authenticator might also work, this contradicts the official documentation and the overwhelming community consensus that Duo Mobile is the specifically supported application for Snowflake's default MFA service. The other options (Okta Verify, Microsoft Authenticator, Google Authenticator) are alternative MFA apps that are not directly integrated with Snowflake's default MFA offering.
