In the bubble sort algorithm, the following code accomplishes swapping values in elements at positions index and index + 1.
A) list[index] = list[index + 1]
List[index + 1] = list[index]
B) list[index + 1] = list[index]
List[index] = list[index + 1]
C) list[index] = temp;
List[index] = list[index + 1];
Temp = list[index + 1];
D) temp = list[index];
List[index] = list[index + 1];
List[index + 1] = temp;

The code provided in option D uses a temporary variable to store the value of the element at the current index before it is overwritten by the value of the element at the next index. This ensures that the value at the current index is not lost during the swapping process. Therefore, option D is the best choice for swapping values in the bubble sort algorithm.
