Answers
D.
Snowflake will first check the current schema, and them the PUBLIC schema of the current database.
Suggested answer: D

Explanation:

Object Name Resolution: When unqualified object names (e.g., table name without schema) are used in a UDF, Snowflake follows a specific hierarchy to resolve them. Here's the order:

Current Schema:Snowflake first checks if an object with the given name exists in the schema currently in use for the session.

PUBLIC Schema:If the object isn't found in the current schema, Snowflake looks in the PUBLIC schema of the current database.

Note: The SEARCH_PATH parameter influences object resolution for queries, not within UDFs.
