Selected Answer: A
Cannot be D...ascending - true syntax is incorrect. if the optional ascending parameter is supplied, it should be ascending = True...False for descending. By Default, sort method is ascending...so it's A

no. Only A. D would work if it was "ascending = True". "ascending = true" is not a valid statement.
