The answer is A. The program prints:
[3, 7, 12, 33, 35, 37]

Why?
sort() puts the list in order, smallest first. It changes the list itself.
The code again
scores = [35, 3, 12, 33, 7, 37]
scores.sort()
print(scores)
Try it: change one number in the program and predict the new output before you run it.
