Correct Answer
B. RESUMABLE_TIMEOUT

Explanation
RESUMABLE_TIMEOUT is the correct answer because it is a parameter used to enable resumable for an instance. Resumable timeout allows a database operation to be suspended and resumed later if it exceeds a certain time limit. By setting a value for RESUMABLE_TIMEOUT, the database will automatically suspend the operation if it exceeds the specified time, giving the opportunity to the user to decide whether to continue or terminate the operation.

This parameter ensures that the redo logs are successfully archived to at least the specified number of destinations before the database can continue processing.

By setting attributes, the scheduler can prioritize certain jobs over others based on specific criteria or requirements.

By following the advisor's recommendations, the database can optimize the access path and reduce the time needed to execute the SQL statement.
