Right answer is (c) Both Type 3 and Type 4 Best explanation: In a Type 3 driver, a three-tier approach is used to accessing databases. The JDBC clients use standard network sockets to communicate with an middleware application server. In a Type 4 driver, a pure Java-based driver that communicates directly with vendor’s database through socket connection.
