Suggested answer: C

Explanation:

A virtual warehouse in Snowflake is used to perform data processing tasks that require computational resources, such as queries that modify data or perform significant computation. Of the options provided:

C . INSERT INTO TBL_EMPLOYEE(EMP_ID, EMP_NAME, EMP_SALARY, DEPT) VALUES(1,'Adam',20000,'Finance'); This SQL statement performs a data modification operation (DML) by inserting a new record into the TBL_EMPLOYEE table, which requires computational resources provided by a virtual warehouse to execute.
