A double linked list allows the navigation in both forward and backward directions.a.TRUEb.FALSE

The correct answer is a. TRUE.

Explanation:

A doubly linked list is a data structure where each node contains three components: a data field, a pointer to the next node in the sequence (commonly referred to as the "next" pointer), and a pointer to the previous node (commonly referred to as the "prev" pointer). This structure allows traversal in both directions—forward (from the head to the tail of the list) and backward (from the tail to the head of the list).

In comparison to a singly linked list, which only allows navigation in one direction (from the head to the tail), the doubly linked list provides enhanced flexibility and efficiency for certain operations, such as deletion and insertion, by allowing easy access to both preceding and following nodes. Thus, the statement accurately describes the functionality of a doubly linked list.
