The answer is B. The program prints:
[40, 35, 19, 15]
This answer was checked by running the program for real.
Why?
sort() puts the list in order, smallest first. reverse=True flips it, so the biggest comes first. It changes the list itself.
The code again
scores = [35, 40, 19, 15]
scores.sort(reverse=True)
print(scores)Try it: change one number in the program and predict the new output before you run it.
