Correct Answer (Detailed Explanation is Below)
A. Updating
Detailed Explanation
Updating means modifying the value or information stored in an existing element. For example, changingA[2] from 10 to 25 is an update operation and does not necessarily change the number of elements. Updating is common in arrays, linked lists, trees, hash tables, and database records. It is different from insertion, which adds an element, and deletion, which removes an element. The complexity of updating depends on how the data structure provides access to the target element.
