The answer is C. The program prints:
ping-zap-bit-pong
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 = ["ping", "zap", "bit", "pong"]
print("-".join(sounds))Try it: change one number in the program and predict the new output before you run it.
