When you tap or click the start debugging button, the program is compiled and saved, and then is run on the computer.
The correct option is A, "compiled". When a program is compiled, it is translated from the high-level language that the programmer writes in into machine code that the computer can execute. This process results in an executable file that can be run on the computer.
Option B, "imported", refers to bringing in code from other modules or libraries into a program, which is a separate concept from compiling. Option C, "linked", refers to the process of combining object files produced by the compiler into a single executable file, which is also related to compiling. Option D, "executed", refers to the final step of running the compiled program on the computer, which happens after it has been compiled and saved.
