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