Doubly-linked list is a type of linked list where each node has two pointers, one pointing to the previous node and another to the next node. This allows for traversal in both forward and backward directions. Circular linked list is a type of linked list where the last node points back to the first node, forming a loop. This allows for iterating over the list indefinitely. Backward linked list is not a standard term used in computer science and does not refer to any specific data structure. Therefore, the best choices are a) doubly-linked list and b) circular linked list.
