The answer is B. The program prints:
[6, 8, 10]
This answer was checked by running the program for real.
Why?
range(6, 12, 2) counts from 6 in steps of 2 and stops before 12.
The code again
print(list(range(6, 12, 2)))
Try it: change one number in the program and predict the new output before you run it.
