Answer 1

The algorithm that will run in constant time is:

**accessing an element of an array**

Accessing a specific element in an array by its index is done in constant time, O(1), because it directly calculates the address of that element. The other options involve operations that depend on the size of the array, thus they do not run in constant time:

- **Binary search on a sorted array** runs in O(log n) time.
- **Sorting an array** generally runs in O(n log n) time (with some exceptions depending on the sorting algorithm).
- **Traversing an array** runs in O(n) time, as you must visit each element.

So, the correct response is accessing an element of an array.
