D Correct answer
Explanation

When the web server and DBMS are on the same machine, all JDBC driver types can technically be used. Type 1 (JDBC-ODBC bridge) works locally, Type 2 (native API) can connect directly, and Types 3 and 4 (network protocols) can connect via localhost. The question's architecture constraint doesn't eliminate any driver type in this scenario.
