The answer is D. The program prints:
boop-bit-zap-beep
This answer was checked by running the program for real.
Why?
join glues the items of a list together, putting ‘-‘ between each pair.
The code again
sounds = ["boop", "bit", "zap", "beep"]
print("-".join(sounds))Try it: change one number in the program and predict the new output before you run it.
