Answer: Secure User-Defined Functions (UDFs)

The correct answer is C (Secure User-Defined Functions) based on Snowflake's official documentation for data sharing. According to the community discussion and referenced documentation, Snowflake allows sharing of the following database objects with other accounts: Tables, External tables, Secure views, Secure materialized views, and Secure UDFs. The community discussion shows strong consensus for option C with multiple comments referencing official documentation and receiving upvotes. Option A (Tasks) cannot be shared as they are workflow objects. Option B (Pipes) cannot be shared as they are data loading objects. Option D (Stored Procedures) cannot be shared through Snowflake's native data sharing feature.
