正解:B
Since the statement seems to imply that a sort operation involving department names and an average salary (AVGSAL) was executed, the best logical inference, given typical SQL query behavior and assuming a typical structure, is:
B . sorted by DEPARTMENT_NAME and AVGSAL: Generally, when SQL queries involve grouping and aggregation, the ORDER BY clause (if explicitly mentioned or implied in your statement details) would sort by the grouping column first (DEPARTMENT_NAME) and then by any aggregated column such as average salary (AVGSAL). This order ensures that within each department, the rows are sorted according to the average salary.
