B
Correct answer
Explanation
The PRTY (priority) parameter in JCL is used to modify a job's execution priority. PRIQTY is for primary space allocation, JOBCLASS assigns job classes but doesn't directly set priority, and RUNTIME is not a valid JCL parameter for priority modification. PRTY allows specifying a numeric priority value within the allowed range.
