The statement that is true for a doubly linked list compared to a singly linked list is: "It allows traversal in both forward and backward directions."

Here's why:

1. "It consumes less memory." - This is false. A doubly linked list consumes more memory than a singly linked list because it has an extra pointer to store the address of the previous node in addition to the next node.

2. "It allows traversal in both forward and backward directions." - This is true. In a doubly linked list, we can traverse in both directions (i.e., we can go to the next as well as the previous node), which is not possible in a singly linked list.

3. "It does not use pointers." - This is false. Both singly linked lists and doubly linked lists use pointers to connect nodes with each other.

4. "It has faster insertion and deletion at the end." - This is false. The time complexity for insertion and deletion at the end is the same for both singly linked lists and doubly linked lists. However, operations at the beginning of the list are faster in a doubly linked list.
