B.PreparedStatement pstme=con.prepareStatement(“insert into EMP
(EMPNO,ENAME)values(?,)”);
Pstmt.setInt(1,”7”);
Pstmt.setString(2,”Admin”);
C.Statement stmt=con.createStatement(“insert into EMP(EMPNO,ENAME)values(7,’Adnmin’));
D.PreparedStatemen stmtl=con.prepareStatement(“insertintoEMP(EMPNO,ENAME)values(7,’Amin’));
