C Correct answer
Explanation

A REGION parameter on an EXEC statement is considered only when there is no REGION parameter specified on the JOB statement. If the JOB statement has a REGION parameter, EXEC-level REGION parameters are ignored. This is because the job-level REGION establishes the overall memory allocation for the entire job, and individual steps cannot override it. Option A is incorrect because EXEC doesn't override JOB. Option B incorrectly suggests EXEC can always limit space. Option D is incorrect because EXEC REGION values don't sum to anything - they're simply ignored if a JOB REGION exists.
