Answer: Python Puzzler #3010

The answer is A. The program prints:

[2, 4, 6, 8, 10, 12, 14]

This answer was checked by running the program for real.

Why?

range(2, 15, 2) counts from 2 in steps of 2 and stops before 15.

The code again

print(list(range(2, 15, 2)))

Try it: change one number in the program and predict the new output before you run it.
