D Correct answer
Explanation

SQL Server recovery models control logging behavior. In Simple recovery, bulk operations like BULK INSERT are minimally logged for performance - only page allocations are logged, not individual row changes. Full recovery logs all operations completely. Bulk-Logged recovery minimally logs bulk operations but fully logs other transactions. Option D is correct because Simple recovery specifically uses minimal logging for bulk operations to reduce log space and improve performance.
