Suggested answer: B

Explanation:

In Snowflake, stored procedures and User-Defined Functions (UDFs) have different invocation patterns within SQL:

Option B is correct: A single executable statement can call only one stored procedure due to the procedural and potentially transactional nature of stored procedures. In contrast, a single SQL statement can call multiple UDFs because UDFs are designed to operate more like functions in traditional programming, where they return a value and can be embedded within SQL queries. References: Snowflake documentation comparing the operational differences between stored procedures and UDFs.
