a) Singly linked list
b) Doubly linked list
c) Circular linked list
d) Array implementation of linked list
Answer: d
Explanation: Arrays provide random access to elements by providing the index value within square brackets. In the linked list, we need to traverse through each element until we reach the nth position. Time taken to access an element represented in arrays is less than the singly, doubly and circular linked lists. Thus, array implementation is used to access the item at the position n.
