What would be the expected output of the following code? def even_numbers_only(mixed_list): Takes in a list and returns a list, but are they the same? for index in range(Len(mixed_list)): if mixed_list[index] % 2 != 0 : mixed_list[index] = mixed_list[index] * 2 return mixed_list num_list = [7, 2, 3, 1, 8] even_numbers_only(num_list) print(num_list) O [14, 2, 6, 2,8] O [7,2,3,1, 8] o [] O [14, 4, 6, 2, 16]
