In Python (and many other programming languages), lists are zero-indexed, meaning that the first element is at index 0.

For the list [a, b, c, d], the indices of the elements are as follows:

  • Index 0: a
  • Index 1: b
  • Index 2: c
  • Index 3: d

Since there are only 4 elements in the list, the valid indices are 0 to 3. Therefore, index 4 does not exist in this list.

The correct response is: There exists no element at index 4.
