Answer: Account

The ALLOW_CLIENT_MFA_CACHING parameter can only be set at the ACCOUNT level in Snowflake. This is confirmed by the official Snowflake documentation referenced in the community discussion, which shows that this MFA-related parameter is an account-level parameter. The community discussion shows 100% consensus on answer A with 4 upvotes, indicating strong agreement. Other options (Role, Session, User) are incorrect because this parameter controls MFA caching behavior across the entire account rather than being configurable at more granular levels.
