Responses

the element d

There exists no element at index 4
There exists no element at index 4

the element b
the element b

the element a

Answer 1

In Python (and many programming languages), list indices are zero-based. This means that for a list of four elements like `[a, b, c, d]`, the indices are as follows:

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

Since there is no index 4 in a list of four elements, the correct response is:

**There exists no element at index 4.**
