The operation that is most efficient in a doubly linked list compared to a singly linked list is the deletion of the last node.

Here's why:

1. In a singly linked list, to delete the last node, you would have to traverse the entire list from the beginning to the second last node, then change the next pointer of the second last node to null. This operation takes O(n) time, where n is the number of nodes in the list.

2. In a doubly linked list, you can delete the last node in constant time, O(1). This is because the last node can be accessed directly through its previous node's 'next' pointer. You just need to set the 'next' pointer of the node before the last node to null and delete the last node.

Therefore, the deletion of the last node is more efficient in a doubly linked list compared to a singly linked list.
