Correct Answer (Detailed Explanation is Below)
C.
Random access to elements using an index
Detailed Explanation
Random access is one of the major advantages of an array. Since array elements are stored in
contiguous memory locations, the address of any element can be calculated directly using its index. Therefore, accessing
A[i] normally takes
O(1) time. Arrays generally store elements of the same data type. Insertion or deletion at an arbitrary position can require shifting elements, making those operations
O(n) in the worst case.
