The answer is A. The program prints:
[5, 6, 21, 24, 30, 47]
This answer was checked by running the program for real.
Why?
sort() puts the list in order, smallest first. It changes the list itself.
The code again
scores = [24, 30, 21, 47, 5, 6]
scores.sort()
print(scores)
Try it: change one number in the program and predict the new output before you run it.
