The answer is C. The program prints:
[2, 5, 8, 11, 14, 17]
This answer was checked by running the program for real.
Why?
range(2, 20, 3) counts from 2 in steps of 3 and stops before 20.
The code again
print(list(range(2, 20, 3)))
Try it: change one number in the program and predict the new output before you run it.
