The answer is A. The program prints:
[7, 38, 39, 40, 45, 46]

Why?
sort() puts the list in order, smallest first. It changes the list itself.
The code again
scores = [40, 7, 46, 38, 45, 39]
scores.sort()
print(scores)
Try it: change one number in the program and predict the new output before you run it.
