A Correct answer
Explanation

The correct answer is A (WORK-FILE). In the SORT syntax, the sorting key (ACCOUNT-NO) must be declared in the WORK-FILE, which is the temporary work file used during the sort operation. The WORK-FILE is defined in the SD (Sort Description) entry and contains the record description with the sort keys. FILE-NAME-1 and FILE-NAME-2 are the input and output files, but the key declaration belongs in the work file specification.
