How Resumable Space Allocation Works
The following is an overview of how resumable space allocation works. Details are contained in later sections.
A statement executes in a resumable mode only if its session has been enabled for resumable space allocation by one of the following actions:
The RESUMABLE_TIMEOUT initialization parameter is set to a nonzero value.
The ALTER SESSION ENABLE RESUMABLE statement is issued.
Apologies. The above is for session not instance as required by the question so answer is indeed C & D.
