To answer this question, we need to understand the different types of JDBC drivers and their functionalities.
Option A) Pure Java - This option is incorrect because pure Java drivers do not rely on any external libraries or drivers to communicate with the DBMS. They use a protocol directly supported by the DBMS.
Option B) JDBC-ODBC Bridge - This option is correct because the JDBC-ODBC Bridge driver allows Java programs to communicate with the ODBC (Open Database Connectivity) driver of the DBMS. The bridge acts as an intermediary between the Java code and the ODBC driver, allowing Java programs to access databases through the ODBC interface. This driver is commonly used when there is no specific JDBC driver available for a particular DBMS.
Option C) Native-API - This option is incorrect because Native-API drivers are specific to a particular DBMS and communicate directly with the DBMS's native API. They do not rely on the ODBC driver to establish a connection.
Option D) JDBC-net - This option is incorrect because JDBC-net drivers are used for communication between a Java program and a remote DBMS over a network. They do not rely on the ODBC driver.
The correct answer is B) JDBC-ODBC Bridge. This option is correct because it allows Java programs to communicate with the ODBC driver of the DBMS, acting as a bridge between the Java code and the ODBC driver.
