The question asks for the minimum role required to set the ENABLE_ACCOUNT_DATABASE_REPLICATION parameter. According to Snowflake documentation and the community discussion with strong consensus (80% selecting D, multiple upvoted comments citing official docs), only the ORGADMIN role can execute the SYSTEM$GLOBAL_ACCOUNT_SET_PARAMETER function to modify this parameter. This function specifically requires organization-level privileges that only ORGADMIN possesses. While ACCOUNTADMIN (A) has broad account-level privileges, it cannot perform organization-level operations like enabling account database replication across the organization. SECURITYADMIN (B) and SYSADMIN (C) have even more limited scopes and cannot modify global account parameters.
