A Correct answer
Explanation

In JCL, when both STEP-level and JOB-level libraries are specified (STEPLIB and JOBLIB), the STEP library takes priority. The system searches the STEP library first, then falls back to the JOB library if not found. This allows step-specific overrides of job-wide libraries. Option A is correct.
