Question

Responses

the element d
the element d

the element a
the element a

the element b
the element b

There exists no element at index 4

Answer 1

In a list with elements [a, b, c, d], the indices are as follows:

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

Since the list has 4 elements, the valid indices are 0 to 3. Therefore, there exists no element at index 4.

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