Option E is the most appropriate. It grants 'CREATE FUNCTION' on 'FUTURE FUNCTIONS' in the 'ANALYTICS' schema, meaning any new UDFs created will automatically grant the privilege.
This ensures future users with the 'ANALYST role can create UDFs. Granting USAGE' on the schema is necessary for the 'ANALYST' role to be able to access and interact with the schema, including creating UDFs. The use of 'FUTURE FUNCTIONS' grants is crucial for fulfilling the requirement of automatically granting privileges to new users. The USAGE on SCHEMA is necessary for analyst to use the database and to interact with the schema, so they can create UDFs. Option A is incorrect as it gives GRANT CREATE FUNCTION on schema, but not FUTURE functions inside that schema. Similarly Options B and D are also incorrect for this reason. Options B and D also unnecessarily grant USAGE on the schema to the DATA SCIENTIST. The data scientist already inherits privileges as part of hierarchy.
