The answer is C. The program prints:
[12, 22, 23, 24, 25, 36]

Why?
sort() puts the list in order, smallest first. It changes the list itself.
The code again
scores = [23, 36, 25, 24, 22, 12]
scores.sort()
print(scores)
Try it: change one number in the program and predict the new output before you run it.
