Problem:

When the source code for a Java program is ready to be run

the source code is run directly on the computer, just as it is
the source code is compiled into machine code first, and then that code is executed
the source code is run by an interpreter
the source code is compiled into bytecode first, and then that bytecode is interpreted

The correct answer is d.

Java source code is compiled into something called bytecode, which is then interpreted by a Java Virtual Machine running on your computer.
