How many of Connection, Driver, and DriverManager are JDBC interfaces included with the JDK?.
C.
Connection is an interface for communicating with the database.
Driver is tricky because you don't write code that references it directly.
It is a JDBC interface.
DriverManager is used in JDBC code to get a Connection.
However, it is a concrete class rather than an interface.
Since Connection and Driver are JDBC interfaces, Option C is correct.
